@popey

Twitodon seems a bit over complicated, there's a lot of text and it requires logging into Mastodon as well

I've been using Fedifinder, which just requires access to Twitter: fedifinder.glitch.me/

@rubenwardy I've used both, I could swear fedifinder found more accounts as well but I might be wrong.

The more ways folks to find each other, the better.
