Indeed Twitter has seen a resurgence among the (serious) AI crowd in particular. For example Bluesky (not to mention the fediverse) can get aggressively negative towards authors posting what seem to be pro-AI posts.

Ignoring the political issues, my problem with Twitter is more prosaic: the character limit is too short for basically anything of substance. I really don't like the thread style it effectively forces.

(Oh, and the new name is unbelievably stupid. I ain't never calling it that.)

Can you elaborate? My personal niche was very popular on twitter until Elon bought it and everyone left, now I don’t know anyone still using twitter who was in that niche.

I don't know which bubble you're in, but since Elon took over, Twitter became absolutely unusable.

The decline happened with bots flooding the platform, with the "creator reward" program rewarding meaningless engagement bait, and with people who I respect in the Tech bubble leaving the platform, which led to an even faster decline.

That was just not the case before the takeover; back then, you would enjoy scrolling through it, engage in authentic conversations, and learn a thing or two.
