So I just joined the Post waiting list out of curiosity. I suspect Mastodon is more my speed. But the two things that intrigue me are 1) a space for writing things somewhere between tweets and blog posts, and 2) who is on there -- I feel like I've recreated an academic community on here pretty quickly, but I miss policy folks who might be over there.
I doubt I'll move, but I'm interested in what others' experiences have been so far.
