I don't know if that's true yet, but there are a lot of FOSS and infosec and other software people on Mastodon. Centrist politics seems to be gradually migrating to Threads; lefty politics seems to be going to Mastodon. I'm starting to see Mastodon and Threads embeds where you'd expect Twitter embeds on mainstream sites.

Twitter isn't dead yet, but it's no longer the universal town square, and the longer Musk controls it, the further away from that it will get.

A quick search on Algolia is showing a lot more links to twitter, but only a minority of them with enough points to have made the front-page. By contrast, the majority of links to fosstodon.org and hachyderm.io have front-page worthy scores, and mastodon.social is 50/50.

Not to sound like a gatekeeper, but it feels Twitter is still appealing for the /r/startups crowd, "indiehackers" influencers and wannabes. The center of "real" tech talk has moved away from twitter.
