I honestly just wish the internet would go back to individual forums. Lemmy is great for a reddit alternative, but I think old school forums were just better overall
I know forums still exist, obviously, but they're kind of shitty right now.
NodeBB and other forum software have added activityPub integration on their
dev roadmaps, so you might see it become a thing again. Personally I don't want to create a new forum account for every thing I'm interested in.
Reddit SEO captured them. They got shitty because they stopped growing, and when a community stops growing, it decays. And yes. They're absolutely better
I believe that most of the things people do, or try to do, on reddit (and therefore reddit alternatives) just aren't appropriate for how the site is structured. Reddit is a 'link aggregator', that's what it was designed for. People post links to content.
So it's no surprise that forums are a better option, structurally, for a ton of communities.
