These sorts of takes drive me crazy, because the concept is really easy: Mastodon is like a bunch of twitters that talk to each other.
Easy mode: Join Mastodon.social.
Normal mode: Pick an instance based on your interests.
Hard mode: Run your own instance.
I mean, the largest instance is randos, and one of the next largest is sex workers. This isn't rocket science.
Do we do a disservice by trying to start everyone at normal mode?
