I think email's a fine way to communicate that gets a bad rap either because: spam, google et al. making it harder to host your own mail server, actually people just hate work email because they don't like work (reasonable).
So I feel bad for all the mastodon people who are saying "it's like email" and how basically everyone is going to have a negative reaction to that even though it should be reasonable and good. It was nice when everything used XMPP and I could just use Adium to chat
