X is so large that it can simultaneously be a giant dumpster fire, the most toxic social network ever to exist, and still have room for honest discussion and good communities.

Gives me some hope for Bluesky, etc. I don't think you need to be Twitter scale or have global network effects to work. Your community just has to choose a particular platform and show a preference for it. You get miniature network effects once your community adopts it.

So if your favorite community doesn't like a particular platform, I don't think they're stuck there, just because it's the one with global scale. They just have to organize an exit.
