I also don't understand why people are giving them a hard time for raising an angel round while having supposedly so little. They have one founder who's already proven himself and another that was writing books for O'Reilly at age 16. And it's not like angels are expecting that you have a finished product, let alone a finished company at that stage.
I think it must be some reaction to getting so much press so early (Pogue wrote a glowing review in the NYT).
