But why haven't they posted on Mastodon in two years
https://mstdn.social/@TheGuardianBecause Mastodon and the entire Fediverse is infested with the most rabid sort of users that even Twitter couldn't stomach and has turned a blind eye to this fact? I mean, there's a reason why they keep getting brought up over and over and people continually nope out of signing up over there. They've got a demographic problem, they refuse to acknowledge it, and it's killing growth. Why would any media outlet want to participate knowing that?
Half of Mastodon seems to be an obsession with what's in your trousers or what you prefer to sleep with.
Mastodon does not have an automated feed like Twitter does, so what you see in your feed is people you follow and their boosts. Just don't follow people who are interested in your sex life.
Personally, I don't want to follow people, I want to follow subjects. I want to read Jay Expert's posts on their speciality without their posts on politics and breakfast. Maybe Bluesky feeds will make that possible (in which case Bluesky kills Reddit).
