Diki is a peer-to-peer (or better: friend-to-friend) network for social semantic web application. Think of it as an instant messenger program for social networks like del.icio.us, bibsonomy, citeseer, facebook or studivz. Unlike those social networks, diki does not have a central server that stores your private data. The idea of diki is to create a social network that respects the users' privacy but giving them all functionality that server-based social networks have. In the current release you can create bookmarks, tag them and invite friends. Then you can search for bookmarks in your friends-network.
