My girlfriend coorganizes with friends a small christmass concert for other friends. It's always an amazing event that pushes you instantly into a christmass mood. And because I can't sing or play any instrument I decided to help with something I can actually do. I created a web with info about the concert, about performers and about each performed song.
I love opened and federated technologies, so I was looking for opened social network. I wanted someting that works the same as E-mail does. Everybody can choose if his E-mail account will be hosted on Gmail or for example on Yahoo or if he builds his own E-mail server. Because it doesn't matter where man signs up. Message from user on one provider will find it's way to to mailbox of other user on different provider.
