#Mastodon has significant usability issues (mostly web) to overcome before it'll be interesting to the mainstream. "Enter your username@domain you want to act from" is confusing to normal people. They already logged in; the system should know that. "Older posts from other servers are not displayed." Why not? Federated instances add inherent complexity. For geeks, its worth that complexity. For the masses, it's not. I appreciate the technical reasons; they don't matter to most people.
