Simpatico Networks - so far there are no blog posts about them.
They link out to the who's who of social media on the blogoshpere from their Social Networking 2.0 including ClayShirky, danah boyd, Dave Weinberger, Many-to-Many, Ross Mayfield, Stowe Boyd - my friend Jerry Michalski and Wikipedia.

Seems like their current implementations are focused on different faith communities.
