I miss the phpBB days. I was on some great forums and content was curated by people who were passionate about the topics. There were serious spaces, silly spaces, helpful spaces, and malevolent spaces. Google still did a decent job of surfacing real, user-generated content back then. You could always refine your search further to find niche information and that just doesn't work anymore. Everything is brand names and every company is trying to make their brand a verb.
This recent rebellion between platforms and communities has been interesting to watch. Communities are not locations in cyberspace, they're still people. Now, with the fediverse, thanks to open-source developers and the kind souls who coughed up some dough for server costs, we now have more choices of where we congregate online. I love threaded topic-based conversations so something like this place is exactly where I want to be. I think this unrest may level out in our favor, but if there's a potential for evil, some arrogant jackass will take it, so I don't expect it'll be an easy journey. Enjoying the wild west feel you pointed out, very 90s!
