    Hi,

    I'm the author of the original piece which was originally penned to warn Quora that their social software design seemed purposely designed to drive evaporative cooling. With the benefit of 15 years of hindsight, Quora has thoroughly evaporatively cooled to an extent beyond even my imagining.

    Isn't this model a bit outdated with prevalence of likes and retweets?

    Users on modern social platforms optimize output to maximize favorable responses, thereby gratification. There are not really ceilings, barrier to entry, or way around the system, so it's resistant to spams and manipulations.

    Classical BBS systems did have this problem. It was said that a community beegins with interesting people posting interesting topics, then uninteresting people joins to read interesting topics, and ends when uninteresting people starts posting uninteresting topics.

    What was missing was feedback signaling, and social media got past this at some point during 2010s.

      I feel like we must be using different internets. Spam and manipulation are rampant on social networks lately, far beyond what they used to be, and while there aren't really barriers to entry there absolutely are barriers to reach: you're not as widely followed as the spammers, your stuff will be drowned out.

      As evidence I offer: any cursory glance at Facebook or Twitter, both of which have likes and retweets.

        I can't shake off the thought that this statement might be more truthful than it deserves to be. Some of social media accounts are closer to what you have described, some are more like what I have. The Dead Internet Syndrome must be not spreading uniformly, but there must be significant disparity across fields and bubbles, deepening divides between common folks without clean freshwater supply and those privileged that has access to spam-immune input source.

        My Twitter timeline is... not great, not terrible. Reddit is out of question.

        • rcpt 1 day ago
          Reddit you have control over your timeline. The comments can be good to. Just stick to your interests.

          Twitter turned into garbage when Elon decided to make it pay-to-play. Giving Blue Checks ranking boosts and extra power when they block others ruined every reply section. On any even vaguely political tweet you now have to scroll forever through a bunch of illustrated profile pics hurling insults before you can get to a real discussion.

          • numpad0 1 day ago
            No. Reddit has zero manipulation resistance. Votes aren't working, and its users are too prone to manipulations too. Tangentially and thankfully, current Internet manipulation frameworks appear to have been built for Reddit and its users; it sticks out elsewhere, and those malicious users at individual levels are easy to bump over edge for anyone with experience in other Internet communities.

            Twitter is o-kay. They seem to have largely gave up investments on African-Indian spammer program and it's on its way out. Gratification mechanisms outside of the feedback loop such as paid boosts and reward cash are clearly detrimental to creator performance, so they were destined to be filtered out. Pushing blue check contents is like pushing AI clips in style of Tarkovsky to TikTok junkies, it never works.

            I think Twitter users by this point as a collective consciousness must have learned that weaponizing Bluesky/Mastodon transition to trivialize corporate influence is a viable short term strategy, considering how slow and tame changes on the platform has lately been. Twitter had always had such mutually toxic and manipulative relationship between the company and its users.

            Twitter has been garbage for a long time before that.

        • Groxx 1 day ago
          There are pockets of Internet that are still great, definitely. But "likes and retweets" are long-time major features of basically all of the absolute biggest social sites in the world, and they're also some of the most awful ones that people keep looking for ways to leave. So no, I don't think it's particularly outdated. Predictive, if anything.
      • MichaelZuo 1 day ago
        Aren’t ‘barriers to reach’ pretty much necessary beyond a certain scale?

        Since a pure chronological feed would be unusable for anyone following more than a few dozen people.

        Or for anyone searching any terms more popular than the most obscure niches.

        So there has to be some system deciding winners and losers effectively.

        • numpad0 1 day ago
          GP's point is that organized spamming had defeated algorithms and contributing/consuming organic high quality contents is no longer viable. I think that depends.
          • Groxx 1 day ago
            No longer viable for many / for new entrants on the majority of the social internet, which is facebook, twitter, etc other giga-sites. You can do it if you have other means to jump-start your followers (pre-existing popularity elsewhere, $$$$$ advertising, interaction-farming bots, etc), but they're all catering for celebrity accounts ("real" and manufactured, i.e. facebook spammers) and drowning out newbies because that's what drives giga-traffic and giga-advertising money.

            Nobody likes that they are the biggest social internet sites, but they are unambiguously the biggest, by a very large margin, and they like to copy each other's worst profitable parts.

            • MichaelZuo 1 day ago
              This seems like a tautology, by definition most people do not have significant differentiating factors between them.

              Because only the most noteworthy fraction of the population are well… noteworthy.

              So the only reliable factors to boost the vast majority of the population way above their peers would be money, endorsements, etc…

              • Groxx 1 day ago
                It being a difficulty in general in any multi-billion-person environment: seems very likely yes.

                It's not a tautology for a site to bias for it though. That's a decision.

                • MichaelZuo 23 hours ago
                  How do you know for sure they are biased ‘for it’ instead of being roughly on the ball, reflecting the natural gradient?
                  • Groxx 21 hours ago
                    By the massively higher amount of spam and scams on Facebook, compared to IRL.

                    I don't step outside on any random day and get immediately blasted in the face by dozens of One Weird Tricks and AI-generated images of Jesus crossed with shrimp.

                    • MichaelZuo 16 hours ago
                      Have you thought this through?

                      There’s probably over a million literally deranged people on Facebook.

                      Even if you only come across a tiny fraction of them, that’s still way more then you could possibly ever encounter in real life, in one physical community, due to simple probability and population density…

    • jwrallie 1 day ago
      You are assuming that what was interesting for the initial users is exactly the same that is interesting for the increasing mass of joining users, but as you increase the number of users, things that have mass appeal have more likes, retweets, etc. So an interesting but more niche post will potentially receive less average attention than before. Therefore, a niche community loses its defining qualities as the number of users increase.

      For advertisement purposes, total engagement triumphs, so this is perfectly fine and lucrative for the platform itself, but the quality is not necessarily maintained.

      Users on modern social platforms optimize output to maximize favorable responses

      Questionable. If you're paid for engagement (directly or indirectly) there's strong economic incentives to bait and troll people.

      This is nonsense; there are people gaming the system constantly who have to be actively fought. There are whole industries of gaming the feedback. And the feedback process itself distorts the content: it gave us "clickbait" and "youtube face".

      I've been watching evaporative cooling of Twitter happen since the takeover and my move to Bluesky, where new users appear in waves every time some new stupid feature is inflicted on the remaining Twitter users.

      • numpad0 1 day ago
        > This is nonsense; there are people gaming the system constantly who have to be actively fought.

        Twitter has gone past that point years ago, possibly more than a decade ago. It's a warzone of drug resistant attention gamers and wannabes with cash to burn for as long as I remember. Maybe it wasn't as much as it is now during 2007-2008.

        IMO, clickbaits and even wooow faces can be considered improvements so long that judgement criteria with presenters and audiences are aligned. Ragebaits are bad, open mouth brainrot thumbnails are disgusting, but a clear and content representative thumbnails would be good - the differences are not in levels of amplification relative to unmodified baseline, but in directions(is the "Inception braaam" bad? I love it and I think it's same thing as clickbaits.)

        Evaporative effect as laid out in the article is a situation where "players" of social media as a videogame exhausts motives to play it. The game must continuously supply dopamine release to creators, whether by rewarding ever sillier thumbnails stronger or more insightful comments better, to retain useful players for content supply to continue. Again IMO, Twitter had achieved a near steady state cycle of gratification and content drop by architectural design, careful userbase formation, and useful set-in-stone precedents, relatively resistant to sabotaging and/or manipulation.

        Is that entire thing a major net negative to this planet? Maybe. One could just say it and few would differ. It's supercharging scholarly experts across various fields and enabling invasive cultural pressures, so it seems neutral to positive to me.

    • fallous 1 day ago
      Users "optimize output to maximize favorable responses" but favorable to whom? The social platforms define "favorable" as "maximizing attention/engagement" and incentivize accordingly, while users may have a different standard for "favorable." The prior can lead to perverse incentives and aberrant interactions between users.
      • satvikpendem 1 day ago
        Favorable to the poster, if we assume they are posting flamebait to get others enraged or to get more clout among followers.

    This pretty much describes a lot of what I’ve experienced in online language learning communities. A large majority of my friends who eventually reached fluency in their target language ended up leaving or becoming significantly less active over time despite their success. Over time, the quantity of ‘wannabe’ language learners has generally increased and reduced the overall quality of the communities. I used to be completely anti-gatekeeping but my opinion has been slowly changing on this point.

    It is interesting that HN still seems to be very high quality (though I haven’t been using it super duper long to truly judge). Does HN have any healthy gatekeeping mechanisms aside from its (ugly) UI to keep it high quality?

      Yes, the mods.

    • Vampiero 1 day ago

      Aside from the users being elitist egocentric pricks and the frontpage being indecipherable to anyone without a CS formation?

      I don't think so. But yeah the layout is mostly what does it. Before reddit redesigned itself, it wasn't so bad. Normies want Instagram-like feeds to endlessly scroll through, and they don't like reading because it hurts their brains. So they gatekeep themselves.

    • manoweb 1 day ago
      I believe you are confusing "effective" with "ugly" There is only one thing that could improve HN interface, and that is an NNTP mirror feed, so you could use any NNTP client you like.

        Oh no, I truly believe it’s ugly.

        • zanderwohl 1 day ago
          What makes it ugly? It's very functional, straightforward, and minimal. No huge padded tailwind components or anything.

            Have you tried upvoting, or favouriting a post on mobile? It’s borderline impossible without zooming in like crazy, and I still have to check it I saved or accidentally flagged someone’s work.
      • istjohn 1 day ago
        I mean, the upvote buttons could be bigger on mobile.
        • yamrzou 1 day ago
          But it's that friction and all the other small details, that make HN what it is. There is value in permanence, and there is beauty in imperfection :)
        • pjc50 1 day ago
          HN being almost unusable on mobile is probably another kind of gatekeeping feature that has a slight positive effect on quality.

      That’s a different discussion, because this one has the added benefit of being from a cornell.edu domain! /s

        It's worthwhile to link earlier related discussions, and both the original article (now linkrotted) and a direct discussion of it satisfy that relation to me.
  • manoweb 1 day ago
    This has happened on Usenet for a while, according to my experience, and for many years it has been an Eternal September https://en.wikipedia.org/wiki/Eternal_September indeed. However, in the past few years, with many low quality users migrating to other places, and with a higher barrier to entry, good content has returned. I infer there are waves, cycles of evaporation and condensation.
  • nthingtohide 1 day ago
    I have voiced this feature request many times.

    Why don't social networks provide recommendation profile transfer. Sort of like stepping into someone else's shoes. E.g. I would like to view how twitter looks like to Simon Willison. This would also make it easier for people to break through filter bubbles.

    • wizzard0 1 day ago
      Dreamwidth has this feature, agree it's awesome.

      Obviously you don't see private journals someone is reading, still a good way to discover new things.

    Doesn't this complaint assume a strict stack-ranking of contributors, where the "top" person has no reason to stay and thus leaves, and then the new top does the same, etc?

    Which is not at all how actual humans and relationships work. We each bring different value to the table, along multiple dimensions.

    • dredmorbius 1 day ago
      A ranking need not have absolute certainty of be fixed over time to be useful. We could well rank into tiers of contributors or participants. I'd generally suggest that such tiers would likely be roughly exponential, with tier n+1 having m^1 more members than tier n, but also a lower net value.

      (n and m are arbitrary, I'm not insisting on log base 10, and the natural log e might well be a better fit.)

      This is typical of almost all large network functions which exhibit power laws, Zipf functions, or the like.

      Measurement itself is difficult and subject to both cost and error, as well as variability over time.

    • coldtea 1 day ago
      >Which is not at all how actual humans and relationships work. We each bring different value to the table, along multiple dimensions.

      Sort of. In practice there are valuable and less valuable contributors.

      Plus all those multiple dimensions are not of equal value themselves.

  • UniverseHacker 23 hours ago
    I think about this a lot- many of the online spaces I used to enjoy have been completely overrun by people that are a particular combination of mean, ignorant, and 100% sure their opinions on everything are objectively correct and final. Anyone not fitting into those 3 in the same way they do, quickly gets fed up and leaves.

    In particular, I am not sure why people are so mean online. I try to be kind to other people even if I disagree with them, but pretty much cannot find anyplace with other people that feel the same. I feel like it is infecting me, and I am not as kind to other people as I used to be or would like to be. I probably need to just stop talking to people online entirely for my own mental health, and contribute to the evaporative cooling of the entire internet.

      The internet isn’t great for nuance. When commenting or communicating online, I’ve often tightened up my language for succinctness.

      • Lammy 22 hours ago
        Voting/karma systems changed the nature of communication compared to traditional forums. Despite supposedly replying to each other, the participants become mere props for the real conversation which is between each participant alone and the larger crowd.

        does this work? I find when I try the same to be “worse” in some sense, but perhaps I am not “doing it right” for the lack of better explanation…
        • JumpCrisscross 22 hours ago
          Yes. Broadly speaking, in one:many messaging, speaking with conviction (and later qualifying) lands better than constant qualification.
      • UniverseHacker 22 hours ago
        The problem is that the world itself is just too complex that without nuance, you're not talking about anything meaningful- so what's the point?

        On HN this is particularly challenging because we get a mix of experts and non-experts (and people that have different levels of pedanticness) - so almost any possible statement is going to be attacked for both lacking nuance or being too detailed (and frequently both at the same time). However the people here are nicer, more open minded, and more accepting of nuance than most places online.

        • JumpCrisscross 22 hours ago

          To get someone to do something.

          There are very few corners of the internet conducive to debate. (Here is one of the exceptions.)
