For the moment, finding people on #Mastodon that you used to follow on @twitter feels a little bit like finding their stunt doubles.
@JeremyNewberger Try using https://instances.social. It searches your follows to see if any of them have posted a Mastodon profile link - and if it finds one, it'll tell you so you can find them again.
It's also worth updating your bio/pinned tweet on the other site with a link to your profile here to help others find you!
@JeremyNewberger Err, correction - https://pruvisto.org/debirdify/ is the site I meant to link. That's the one that'll find Twitter peeps.
Too many links today! 😅
