On rereading my own remarks, I realize that I was too quick to pass over valid criticism of Mastodon. Sorry about that. In hindsight it was too late at night for me to give a great reply.
I really want Mastodon to succeed. I like it conceptually and have invested more time into discovering other users than I ever did on the bird platform.
But all the criticism @shantini is making is valid. Sadly Mastodon has the flavour of Linux on the desktop. Of course it works, and the enthusiasts are very happy. But the sudden migration to desktop Linux did not happen.
