So wait, Mastodon is broken up into loads of different boards?! Just cos I've signed up to .network doesn't mean I am on other parts of Mastodon?
@rocshot again, like email, different providers may eventually provide attractive features (e.g. Gmail vs. Yahoo vs. running your own personal email server), but right now they're all pretty much the same. It's early days.
But you are trusting your timeline/data to whoever runs the server you joined. I imagine someday I'll migrate to something I trust more, but for now in early days I'm not worrying about it much.
