I respect what Hipmunk is trying to do, but I really doubt they are filling voids outside of "this" community. I find it much harder to scan, slower to load, and having lower quality tools for finding alternate (or cheaper) fares.
It's interesting, considering they will provide round-trip flights and list the London to NY flight(s) as a separate item, which would make me think the data is there.
