I mostly really like Mastodon, especially as a tool for listening to and interacting with the developer community. But the federated bit still bites me, given that I joined at a time when there was a mass migration off of Tw*tter and some of the more popular instances were closed to new accounts. I’m finding that my instance does not support things like editing posts (a thing that other users seem to think is universal!), and I'll be darned if I can figure out how to follow a hashtag.
