@lightone Fediverse originally referred to the OStatus-verse and then, as Mastodon dominated the Fediverse, the term smoothly switched its meaning to OStatus+ActivityPub. Now that ActivityPub plugin for GNU Social is working, I think it's fair to only consider AP-verse as the Fediverse. Referring to Diaspora as a part of the Fediverse is just misleading to new users. That's how I understand the way this term evolved.
