i highly recomend everyone check out the Diaspora project. Its an awesome grassroots project to essentially decentralize social networking....take out the corporate middleman and let each person be their own social seed...something akin to P2P. The project picked up major grassroots fundraising after facebook's latest controversial updates.
It is a project launched by 4 graduating new york university students, and is being funded through another awesome grassroots website called kickstarter.com. They are great for microfunding good ideas.
Ya'll should check it out!
