Say hello with an #introduction if you want. Don't worry about the pineapples. It's "fediverse." It was fediverse before most of us where here, so it's fediverse. It's not really like the birdsite. We call Twitter the birdsite. GNU Social and OStatus and Mastodon are not all the same. Mastodon is to OStatus as GNU Social is to OStatus. Tweets are toots. Retweets are boosts. Or maybe something else, depending. I know. Get over it. Use the CW and NSFW things if your client can. Instances are just servers. Different places running mostly the same code. Nodes, same thing. Federated TL: All the instances your instance (the place you signed up) talks to. Local TL: Just your instance. Yes, hashtags work. DMs: click the little world icon thing. Yes, there are mobile apps. I hear good thinks about Amaroq (iOS) and Tusky (Android). I haven't tried them. Rails and React. Like if email and RSS had a baby.
