My answer might be biased because I've stayed away from "popular" social media hubs for the past 9-10 years, but I don't think I regret it.

There's one thing I love about the web, and it's right there in the name: The web part, how you can jump from one place to another and discover things along the way. I had a bunch of posts, in the currently discontinued newsletter, about how the WWW is awesome, and also posted a discussion here on the forums about the state of the web.
Recently, I also saw multiple posts regarding putting more emphasis on RSS, blogging, and self-hosting. Basically, trying to put back some joy into the web. We had previously tried to gather all nixers members blog feeds but without too much luck, we're trying again right now.

I think that the thread joining all these topics is that people's web consumption has become repetitive and centralized, or to say it bluntly: they're bored. I've had a friend some days ago ask me about my web browsing habits, asking if they could change theirs. They felt stuck in a loop going from link aggregation sites, to Facebook, to Reddit, to Twitter, and YouTube. There's much more to the web than a few websites. Maybe the fact that everyone is stuck at home has made some people realize this.
