David Pogue asks: Are You Hip to Hipmunk?

He was snapped up by M.I.T., from which he just graduated. He interned at Apple, and — well, nevermind. This is all just a way of saying that the kid is a genius, that I’m thrilled to have known him when he was a nobody, and that I have a major conflict of interest in writing about his new project (with a Reddit founder, Steve Huffman): it is Hipmunk.com.

So, I hope you've tried Hipmunk by now :)
