It's simple, Prime Minister: X is for people who think that Britain is about to lock up everyone who isn't woke, Bluesky is for people who think that sounds like a terrific idea, and Threads is for people who have no idea what either of the others are on about.

Truth Social is for people who think they run the Internet, Nostr is for people who think they should run the internet, and Mastodon is for people who actually do run the Internet.
& 4Chan people don’t care as long as they have big tits.
