So we on this cat toot aren't necessarily connected via the federated timeline to all other instances of mastodon, huh?
@TRAVI5TY a subtlety to this: my understanding of it is that you won't see things from other sites on the federated timeline unless someone on tootcat is following that person, causing their toots to get pulled to tootcat.
