@zach There's Fedifinder. I'm not sure if it still works though, I think Twitter revoked API access from it. It still works for some of the other websites it did though. Besides that you should follow the same tags you used to look at on Twitter & occasionally search people's usernames here or check their Twitter account to see if they mentioned where they moved to.

The cross site searching isn't so bad, you just see results from whatever wetdry.world has seen as long as the person posting it has search indexing enabled. If you search "just_a_rock" you should see suggestions for "# just_a_rock", "@just_a_rock", "Posts with 'just_a_rock'", & "Profiles with 'just_a_rock'". If something doesn't appear here I recommend going to the search bar on mastodon.social to try since that's the biggest server & it knows about the most stuff.

Once you find a post you can copy the link to the original copy of it & paste it in the search bar on wetdry.world to have wetdry.world automatically find & cache the post so you can look at it or comment on it. If you find someone's account you want to follow you copy what's under their nickname on their profile & search that, for example mine says "@just_a_rock", it's basically an address that specifies a specific account & what server it's located on. If it doesn't say a server & only has the username it's probably native to the server you're looking at & you should try adding that domain name after the second @.
