Shout out to the hardworking mods and admins who have to weed out the assholes that ride in on every new wave of users.
New users - mute or block things you didn't expect and/or don't want to see, report obvious assholes.
Old users - continue to welcome and educate new users on things like mindfulness through content warnings, or suggesting a different instance might better suit their tastes (remember we always get a lot of people leaving Twitter for a "free speech zone"..)
Follow friends and discover new ones. Publish anything you want: links, pictures, text, video. This server is run by the main developers of the Mastodon project. Everyone is welcome as long as you follow our code of conduct!
