Mike's one piece of advice for new Mastodon users - dive into that Federated column and follow ANYONE and EVERYONE who looks like they've posted anything at all interesting to you. Just hammer the button. There's no penalty for mistakes. Go wild.
Later, when your Home timeline is buzzing, go in and unfollow people you decide you're not enjoying so much now.
Then do that again a few times. Then some more. Forever.
@mike absolutely, but in my circles that’s liable to get you blocked immediately by plenty of people.
Consider this a friendly, local pub. Make yourself at home, bring your friends, have a good time! Meet new people, have a laugh, enjoy the ambience, and the Oxford commas.
