I know diaspora (the social networking thing) has popped up now and again, but I finally made myself an account on http://weleft.com/
and would be happy to have some diaspora 'friends'. I think anyone can go to that URL and create an account, and anyone with diaspora anywhere else should be able to add me via email@example.com
Might also be a nice idea to run a PPUK diaspora service. I don't know if this is something we could charge for - just a minimal amount to keep it running. It might be a way to promote the Party and spread word.
