Incidentally there still seems to be a bit of confusion. Please help us keep our messaging consistent.

What are these things?

Mistpark
a decentralised social network (discontinued)
Diaspora
a decentralised social network
Friendica
a decentralised social network aggregator
RedMatrix
nobody is really sure what this was. Officially a privacy enhanced decentralised publishing platform (discontinued)
Hubzilla
a decentralised community server

Yes, there are people using hubzilla for decentralised social networking. I'm just saying that if somebody asks you what it is, or how it differs from redmatrix/diaspora/friendica; the answer is that it is a community server; and these other projects are what they are, and these things are all completely different. You may elaborate on this description based on the technical grasp of the audience. Calling hubzilla a social network does the project and everybody here a dis-service.
