My Five Faves:

Farmer2Farmer Learning

Because when I asked them why they didn't list themselves in the "education" cause category, they said 'because there's so much more to it than education.' That pretty much sums it up for all of us who seek to engage the social web for collaborative learning and social change.

NCPC-Prevention Communities

Because they engage social web tools for collaborative sharing, identification, and replication of common solutions to common problems.

SFZero

Because it has proven that its platform is capable of engaging people's interactive, collaborative desire to create actions that impact the real world.

TEN-Community of Modern Abolitionists

Because only a grassroots social web movement can wake up people in America to the fact that slavery still happens, including here in America, and create an avenue to do something about it.

ManorMeta

Because participatory media is clearly one of the waves of the future, that can/should be used to bring people together to solve social problems.

Common Element: Virtual Collaboration = Real-world Social Change

It's been thrilling for me to discover so many cool ways of using the social web for social good. My personal criteria for whittling down to five faves is a focus on virtual collaboration that intrinsically results in real-world impact. These five projects have that key element in common with my own project, SElearninggames -- which is why I think they are so cool -- because these other projects affirm what I believe we can do with social web tools.
