Reddit CoFounder Dips Back Into YC With Travel Startup Hipmunk (YC S10)
Not to knock Hipmunk, but this visualization has been available for years as the "graphical view" of ITA Software's matrix demo app:http://matrix1.itasoftware.com/Do a search and then View Flights - Graphical. It's excellent and has been my preferred way to find flights for ages.It's nice to see that someone who might actually care about marketing is offering the same useful tool!
