I couldn't be happier with how this turned all turned out. Great writeups came from all over the web: Mashable, Portfolio, Buzzfeed, thedailywh.at, TODAY show blog, lifehacker, and MSNBC to name a few.
Gizmodo actually took time out from critiquing the latest Gmail advert to say ours is "a cute ad that actually works because it makes fun of the Internet's obsession with cute, rather than catering to it. Here. Take a minute and enjoy this Hipmunk ad."
Huzzah! Thanks to all of you who helped spread the word & continue to evangelize for hipmunk regularly.
