I don’t think either of those are major issues. I happen to think that Mastodon is OK, almost catchy. Their mascot is very cute too. They officially did away with the Toot terminology quite a while ago, like a year or two, but some instances modified the code to keep that, and the old hands keep calling it that too. Also, keep in mind that I said that I fully expect Mastodon to stay a minor but viable player. It’s never going to overtake a corporate behemoth like Meta, and most likely not even Twitter.
I’m not sure I would go as far as saying that the trends are tipping toward smaller communities again, but we can hope.
