Charlie Stross@JorgeStolfi @jupiter_rowland Nope, you got it wrong. Hint: count the number of characters in the toot you just replied to—it's well over 500, because it didn't originate on a Mastodon server! It's a federated system, so every client can read stuff posted on any other server that supports ActivityPub. (Imagine you could read Twitter tweets on your Facebook page. Only more so.) If all you want to do is to toot, that's fine—everyone else can see you just fine.
