I got an invite to friendbinder tonight. It supports adding 7 networks at the moment. One cool thing is that it let’s you pick and choose which of your friends from which networks that you want to view. It even lets you link them together. But it doesn’t offer anyway to get this info out, like a client or rss feed. I know it’s in beta so things will change. The big difference from this and friend feed seems to be that the users you want to follow don’t have to have an account here. So basically it’s just aggregating information that is already there via RSS, same as my friends group in my RSS reader.
