More Crowdsourced Do-goodery

MediaCause.org is a start-up volunteer website that matches marketing professionals with nonprofits who need marketing help.  Pretty clever, we think.  The model is very similar to Sparked.com and the idea behind the original GeekForGood.net.  What makes mediacause different is the 1-3 hour work blocks designed to give volunteer professionals a meeting with a nonprofit to discuss strategy or help untangle an analytics setup stumper or something similiary vexing to a nonprofit with perhaps better things to do. Or at the very least, a nonprofit with perhaps a better way of doing things after a MediaCause.org volunteer session.  We'd be curious to hear from organizations that have benefited from this form of distributed generosity.
