Am I the only one who thinks their business is completely indefensible? I haven't read their patent applications, but I'd be shocked if you can patent not showing information. What they've done is definitely clever, but it seems to me that the big guys could have one decent designer and UI person duplicate their entire business in a week. I should add that I've already booked 3 flights through Hipmunk and recommended it to a bunch of friends. I hope I'm wrong.
