Connecting the Social Graph: Member Overlap at OpenSocial and Facebook

Full story at:

An excellent little report on member overlap between social networking sites. As you might guess, it is huge: 64% of those on Facebook are also in MySpace, for instance (only 20% vice versa, but MySpace is still much bigger). Unless we start finding more ways to aggregate these networks, it is likely that many will die as it is simply too hard to maintain that many profiles and logins for most people. It looks very much as though it will be a stand-off between Facebook and MySpace, but I think that there is still a place for niches, as long as we can mash them up intelligently and the big bad networks don’t fight too hard for proprietary lock-in.
