I've had a Twitter acct for a long time, and I still use it. I've curated my feed to contain virology/epidemiology specialists, independent journalists, and eye candy. I have 2 ways of finding people to follow. 1. When I'm reading on the internet and find something I like, I look to see whether they've got a Twitter acct. 2. If someone comments intelligently on a good post, I check their profile. If they post stuff worth reading, I follow them. As for eye candy, I'm attracted to ancient stuff. There are several archaeologists who post.

I've "followed" several people from Twitter on Mastodon. I can't see them in my feed, but I can view the list of people I've followed and click on them. For now, their Mastodon posts come from bots that echo their Twitter posts. It looks like everyone's hedging their bets. If I need to leave Twitter, I can still access most of the info I'm used to getting from there.

Twitter's not completely a cesspool yet.

Tried Nostr. Mostly crypto.
