Oh that sounds cool. So if someone you follow on Mastodon, that is basically just bot posts of headlines on a news site for example, you can enter their screename there and see if there is an associated RSS feed?
Sometimes they don’t even drop website info in their bio.
Oops, it is your OWN screename you enter. Is it all on the instance, or just those you follow (I haven’t gotten into my noggin how local ‘local’ is yet)
