A lot of the accounts you follow and interact with on here are not Mastodon accounts!
For example, @theatticdwellers is a PeerTube account, @Iancylkowski is a Pixelfed account, @rstv is an OwnCast account.
There are dozens of different server types on here, not just Mastodon servers. When you talk about this place, it's not enough to call it "Mastodon", because it's more than just that.
That's why people call this place "The Fediverse", because that name covers all server types. 
I'd like to interject for a moment. What you're referring to as Mastodon, is in fact, the Fediverse/Mastodon, or as I've recently taken to calling it, the Fediverse plus Mastodon. Mastodon is not a social network unto itself, but rather another free component of a fully functioning federated system made useful by the ActivityPub protocol, web utilities, and vital social network components comprising a full fediverse.
@runarcn There's more to the #fediverse and the #federation than "just" activitypub.
And in so far, no its not "fediverse+mastodon" ... mastodon is just another part within the broader federation.
That's why i'm using friendica... Form here i can connect to DFRN, Diaspora* and AcitvitiPub ;)
FediTips has moved!
