Kurzgesagt

The main discrepancy I see is, it's not actionable. It's like solutions to obesity: yes of course people should exercise regularly and eat a balanced diet, but so long as it's cheap and easy to binge Netflix and eat fast food, hundreds of millions of people will settle into that lifestyle. So long as algorithm-driven feeds are widely available people will flock to them, and so long as they remain profitable they will remain widely available.

The people who want to eschew mainstream social media for smaller forums will do that, but most people won't and the societal issues will remain unchanged. They only way to actually implement change is by eliminating algorithm-driven social media, and how do you even do that?

All those forums and whatnot still exist...they never left.

People just like to be sheep and follow the herds to the company ran/endorsed cesspools where ads are the primary focus.

People listen to companies and believe their lies.

On forums, people maybe be just talking about the thing that the forum is about. For example, if you're on a forum about Minecraft or cats, you're not going to be discussing differing political opinions — in fact, such conversations are usually frowned upon. This is different from your real life community, where you're going to be talking about all sorts of different topics.

A lot of real-life communities restrict discussions about politics too, and for similar reasons to online communities (not wanting to be broken apart by angry discussion). What I got from the video was that positive interaction with somebody you disagree with — even if, or maybe especially if, that interaction isn't actually about the source of the disagreement — is more important than actually facing the disagreement head-on, which usually just serves to make everybody angrier and more convinced of their own points.

My thoughts: I'm in a lot of small communities online (mostly forums and discord servers), and the ones I enjoy the most are the ones that are generally populated by people who have similar worldviews and cultural values, and that prohibit discussion of extreme points from the "other side" — not because I don't want to challenge my worldview, but because I think those communities challenge my worldview more. Spending time in them makes me feel positive about other human beings. I respect the people in them who have different opinions from me, and frequently have conversations with them that change my own opinion a bit.

On the other hand, going into the default feed on a larger social media site is like being hit in the face and then told that I'm supposed to be considering whether maybe I deserved to be hit in the face, really, which isn't something I usually feel particularly disposed to do. Sites like mastodon have enough controls to be able to make your feed into something that at least isn't actively radicalizing, but it means you can't follow anybody who disagrees with you, because those posts will be mixed in with anything from them that you actually do want to see. Your feed isn't like a forum with its own set of social norms about what kind of content is acceptable to post in what context. People you follow can't read the room before they post because the room isn't visible to them in the first place. So I do think that forums are much more conducive to being deradicalizing than a lot of other forms of social media, just because the nature of having distinct communities with separated pools of posts makes it a lot easier to interact with people you disagree with in situations where you agree with and respect them. But it also relies on the forum having the right rules and moderation — just being a forum isn't enough for it to be a healthy and respectful community.

• I think that people should in general embrace all kinds of points of views at least in some way and not just ignore some stuff just because they differ
• I don't have enough experience about the forums and those other tools to speculate any possible effects
• I believe that giving any surrounding for extreme thinking can make it getting out of hand later if not somehow moderated

In my real life communities we tend to forward on too many political sidetracks from whatever we were meeting about too. Not the stifling way, just that we don't need to discuss the Russian invasion of Ukraine while trying to play DnD. We can talk about it after

Forums already fixed the internet back in the 90s. We just undid it. And have to pay the price.

Echo chambers are platform-agnostic I think, so it wouldn't change much going back to forums. I've seen forum-based communities fight about homemade CPU waterblocks.. yeah I don't think they would help much.
That said, I preferred forums to the recent "Get Discord or get ~~fuc~~nothing!" trend.
