Bluesky is "fine" if what you want is Twitter without [as much] fascism. It's a better user experience than Mastodon. The average user doesn't care about federation and all the rough edges where you have to understand technical details in order to understand what's going on is frustrating for them.

I hope Mastodon learns some lessons from Bluesky (curated follow/block lists, and curated feed algorithms) but I still hope federation is the future. Bluesky will eventually enshittify because it has financial backers who want a return and could give a fuck about uses or ethics. But for the time being it's a good platform, and perhaps more importantly the best shot at breaking Twitter, and I will strategically support it while it remains a good alternative.

Rednote I have no idea about. Not happy about Chinese propaganda and censorship, but not any happier about right-wing American propaganda and censorship, so fuck it. I haven't made an account yet but I might at some point. TikTok was by far the best algorithm at delivering what I want to see in the moment, and as I only spent a handful of minutes a day on TikTok on average, that's really valuable.

Insta is useless as you seem to have to curate your feed to only be a single thing. Plus, fuck Meta in the ear. So if Rednote gets the content creators and the algorithm, I'll probably check it out eventually.

Twitter and all its alternatives always tend to get inflated coverage because twitter was essentially the journalists' app, so they write about it more. Bluesky was the first "real" alternative I guess.
