It's quite scary that a company like Google can come along and shit in a startup's cereal practically overnight.
I know we were all rooting for The 'Munk, but it seems that Google's use of Price x Duration matrix effectively steals the thunder from Hipmunk's agony filter.
I mean, it's not as if Google needs the affiliate revenue, and I bet the Hipmunk guys would have preferred it had Google decided to "organise the world's information" through an acquisition. I think I'd need a good cry if this happened to me :(
