welcome to mastodon, newbies. here's an inscrutable list of things you can't talk about here, like "search" or "defederation is a nuclear option". there's also countless other social norms and no we won't tell you about them, people will just get really mad and harass you in the DMs if you don't put a CW on your food or if you have the audacity to complain the UX isn't flawless.

enjoy your stay
