Volunteering & Volunteer Students

This site just launched, but seems like it could be a great model for getting volunteering and communities energized. Check it out whats going on at Change the World Louisville. While its certainly early, I think it has the potential to be a great local model for communities:

We are a group that stepped forward to help on developing the Change the World—Louisville eCommunity We have been working to develop the means to share information on social entrepreneurship and social change.

They even have a social change book club! How cool!

Anyone know of anything similar? I wonder how it could be intergrated with other ongoing work, like Volunteer Match or Idealist.org (for instance via a widget)?
