I have no interest in the things you state, FWIW. The issue I have is that--apparently, based on this and other threads on the software--it matters what server you are on for even basic things like "can I follow another user I actively know about?" or "can I reply to a post from another user I already know about?". I have almost never had issues replying to emails from people I have received, receiving emails from people who intended to send me an email, or being able to send email to someone random I have heard about. These issues DO happen, but they are so rare I can't remember the last time it happened to me, and it has always been to the discredit of one of the two party's email servers... but with Mastadon, people are making it sound like all of this fragmentation is a feature?
