As Twitter self-immolates, I am seeing people I know setting up on Bluesky.

I find this perplexing. Can people really not learn the lesson that a social network owned by a capitalist is a social network they don't control?

You can argue about whether Bluesky or Mastodon has the better technology, but what's 100% clear is that Mastodon is run BY users FOR users. And that difference is the only one that matters in the end.
