@f00fc7c8 @techtraveler - Yea - it was not to be a pedantic :)
I would say though, that Diaspora is part of the fediverse by definition as it was one of the first. I am on both Diaspora, Hubzilla and Mastodon and see many things go from one place to the other.
Mastodon and Diaspora are the most user friendly interfaces and have the largest user bases. They cover facebook style blogging and micro blogging. That they can't connect is just typical FOSS :) Hopefully it will be corrected soon :)
