This is cool. I'm glad people are working in this direction. A common theme that I've noticed among recent upstart social efforts is a focus on platform and/or policy differentiation. I personally believe this is not very important during the phase where a social network is working to reach critical mass. It seems to me that most successful social networks got their start by offering users unique content, by targeting existing, tight-knit communities, or through some combination of the two. Platform and policy help shape the social network, but there needs to be a network to be shaped in the first place - they don't form magically.
