Thanks! Seems like the official Mastodon app lets you search and follow users on here, as well as comment on posts, but not make posts or follow communities… interesting.
Edit: actually, looks like you can follow communities. They show up as reblogs/retweets on the original post owned by the user. This opens up some interesting possibilities, if all you want to do is follow specific communities and comment on them.
A lot of sites like these are already just click farms with “articles” consisting of a headline and a couple poorly-researched sentences. Switching to AI probably won’t significantly change the quality of what they’re churning out.
