It’s a mess. Bluesky and Threads took off a little when each respective app launched and then had upticks in activity when things happened like Elon doing a Nazi salute or whatever so people said I’m leaving twitter!
But, it’s clear that people have just come back to Twitter or stopped using BlueSky/threads. And Twitter is a ridiculous cesspool of bigotry and AI. Like crazy levels. I’m pretty keen on being able to spot/sleuth out AI and the amount now is wild. If you’re engaging in a political conversation on Twitter, and I don’t know why you would, you are almost certainly talking to a bot.
All this to say, I just use everything and try and stay informed while sorting out the crap.
