A startup that is not charging user and still profitable?
patio11: See, I think this question isn't as actionable as you might think it is.  It is like saying "Do you know of anyone who dropped out of high school to play professional basketball and made it to the NBA?"Yes, I do.  I still really wouldn't suggest you try it.  The countries' stoops and prisons are covered with was-a-sure-thing-to-go-pro.  And the Internet has several million sites already hunting for that six figure AdSense check.  (While boring little niche websites with subscriber numbers smaller than many people's Facebook friends list can be ramen profitable within weeks or months of launch.)
