"Mastodon is confusing to use" is something I didn't quite get. I just got a mastodon.social account for lack of any alternative. When I'm on a different server, it presents me with the "enter your home server" if I want to interact. People can understand the difference between @gmail.com and @yahoo.com email addresses.

Is there a list of specific difficulties or speed bumps somewhere? All the articles I can find are just vague "it's too complicated" or list choosing a server as the main prob.
