I think the biggest disadvantage of Mastodon that I've found is that it's *much* harder to find new interesting content since you're limited to searching by a single hashtag, and even that ends up being quite limited depending on the instance...
Follow
Just found <https://mastodon.host/about> which runs a modified Mastodon version that does full-text search, and has a bot that follows lots of people to try to give users as big of a view of the fediverse as possible.
Interesting sounding instance, though I'm not expecting to move there, at least not anytime soon.
