What if you could do some good while waiting on line at the grocery store? The Extraordinaries want to help you help the world by giving you chances to volunteer via their iPhone app.

The project is still in its infancy right now—there were only about 10 active projects when I looked at the app the other day, and most of them were requests to tag photos in big image libraries. And of course there are limits to what can be done in a few minutes on an iPhone, but there’s tons of potential here. I envision volunteers answering questions from school kids, documenting buildings that need to be weatherproofed, reporting on neighborhood meetings for community sites, assisting non-profits with online research ... No doubt as The Extraordinaries build their pool of volunteers and tasks to be done, more and more good opportunities will emerge.

Crowdsourcing has produced some of the best resources available today—like Wikipedia itself—so why not apply the same idea to doing a bit of good? In this short video, co-founder Jacob Colker explains what The Extraordinaries are up to. Want to be a part of it? Get the iPhone app here.
