Google Code just released Social Graph, that uses XFN and FOAF. WordPress supports XFN for a long time. Months ago, I removed blogroll, I thought that was a waste of my bandwidth. Well, it’s the perfect time to bring it back since Google mentioned. I bet you that we will see some uses of this new API in next week on Digg or somewhere else.
