I could post on the fediverse all night long. :( I have to sleep eventually though.
I wish I could get my friends to abandon #Twitter and #Facebook and instead use federated services. Although it's a disingenuous comparison, I think GNUSocial provides a solid microblogging alternative to Twitter.
I also think that #Hubzilla could someday be used as a full-blown Facebook alternative, but Facebook is a kitchen sink with numerous features that is hard for individuals to fully replicate, or even desire to replicate. Even then, creating a 1:1 approximation of something is not reason alone for people to switch.
