More examples? Ok! Say you happen to be someone who's got a knack for spotting rainbows. Challenge a fellow color-lover to spot 10 rainbows in a day, capture them with your iPhone, and whoever reaches 10 first wins. Maybe you're a microbrew lover and your best friends from college, who live in Chicago, New York, Philly and San Antonio, also love a good craft beer.

We love the idea of using challenges as a way to keep up with friends near and far.
