Personally, if there was a service like Bluesky that let you choose your algorithm instead of just being purely chronological, I would jump on that very fast. That's what Bluesky's killer feature is, imo.
Apart from, y'know, not being the hellsite that is Twitter.
I would argue that what makes it good. Mastodon is only as good as you make it but you have to take personal responsibility. That's something that people should get accustomed to taking again.
I would prefer to have Mastodon stay out of the limelight because we might need it after they target BlueSky. Mastodon is safe from attacks by an incoming autocratic administration precisely because it is too small for them to give any fucks about.
the EU has been promoting Mastodon and the fediverse ever since Musk bought twitter, encouraging european governments to use Mastodon as a broadcasting platform and funding it through NGI.
