I've set up accounts on three social media sites to replace Twitter.
CoSo is the clear winner but I need to find a way to attract more journalists and researchers to join for it to be an effective replacement.
Post.news is fine for news updates, but it's funded by Mark Andreesen, who isn't all that different from Musk and indeed helped ($) Musk buy Twitter.
Spoutible is problematic harassment-wise and I only set up an account there to prevent someone else from spoofing me.
@jjmacnab A bunch of journalists are on Mastodon. I'd rather the "broadcasters" not flood CoSo, it's way too nice and friendly and interactive. I have a "news" column on Masto, and that fills in what our best news sources: @TheNewsOwl/@WhiteRose and @WeThePeople and @BreakingNews don't aggregate, although they cover most of the bases for me.
