Recently, I've been spending a bit of time at Omidyar.net.

They state, "We believe every individual
has the power to make a difference.

We exist for one single purpose:
So that more and more people discover their own power to make good things happen."

I've been having some great discussions there and will be posting recaps of some of my posts here.

So, if you're interested in yet another social network system that isn't just yet another social network system, take a look at Omidyar.net.
