I'm trying to keep track of the mass migrations to Mastodon that have happened.

I think it started with:
- early adopters, programmers, FOSS people
- tons of peeps in Japan
- furry community moving off Twitter
- LGBTQ+ folks leaving twitter
- people who saw that polygon article (me) or heard about it when it started getting mentioned on hackernews
- comics/artists leaving twitter
- NSFW blogs leaving Tumblr
- sex workers
- and now, Indian politics Twitter users

Am I missing any big moments?
