I really wanted Mastodon to take off, but none of the people who discuss anything of consequence moved there (because they didn't want to lose their reach). Instead, I only found people in the fediverse that post smalltalk about their daily lives. Which isn't bad! But these people will not be affected by section 230 either way.

Intuitively I expected political dissidents would move off Twitter first, but I can see how the opposite happened instead.

There are also people discussing about programming, current events, politics, etc.

I tried the fediverse, only to find just as many constant reminders of the culture wars there as on Twitter, though the bulk of fediverse servers have selectively federated in order to ensure that views represent one end of the ideological spectrum. If you are the sort of person who prefers to avoid discussions about political and social issues, then the fediverse is no escape.

Wait till it gets more popular. Same as with the whole internet.
