Sparked.com--microvolunteering at its best

Sparked.com asks a few basic questions: What's your favorite cause and in what areas can you help?  You're then sent to project pages of nonprofits that have specific questions.  A hospital in one of the M states needed help with getting people to interact on their Facebook page.  They weren't asking for "likes" and you don't have to "like" them to see the page.  Those who answered gave constructive criticism with 5 star advice.  Another organization asked for people to peruse their blog and give them feedback (on sparked.com) about their posting, layout, etc. Who doesn't like 5 minute volunteering or an open API?
