Chris Zacharias worked at Youtube right? The hilarious thing about this article is that where he says Front-End Engineers he actually means web designers, and Google doesn't have them. It seems obvious to me that to have a good looking website you need good artists, and that #2 and #4 are such revelations speaks volumes to Google's overall lack of respect for that kind of thing.
Though Developer/Test Driven Design seems to be working out for them.
