It Had To Be Poo
In the WSJ, Geoffrey A. Fowler and Amir Efrati write of a new phone app:

iPoo, a social-networking app that connects people sitting on toilets, sounds like a joke, but it exists. More than 200,000 people have paid $1 apiece to download iPoo since it launched two years ago, say the app's creators, enough to help put one of them through Harvard Business School. And tens of thousands use it every day, they say.

"In hindsight it was a great idea, but we weren't expecting it to be anything more than a joke amongst ourselves," says Amit Khanna, a 30-year-old accountant in Toronto. He says one of his fellow iPoo co-creators is ashamed to be associated with it.

In...hindsight...poo hoo hoo.
