We grabbed Dave Morin, Path co-founder and CEO, amid his many press interviews and on very little sleep, to ask some of the harder questions that some are raising about the much-hyped new photo sharing application, Path.

In particular we were wondering why Path took so long, so much staff and so much money to build compared to other apps, and if it’s really solving a big problem. We also ask about whether the company will have a hard time growing thanks to its iPhone-only launch and core belief that more photos will be uploaded if there are tighter controls on who can view them.

I’ll let Morin answer himself in the video below.
