Facebook is so much younger than Google so it's a bit unfair to compare them this way. Facebook is still in such a crazy growth so they simply focus on their core business.

Google started launching their great non-search products (maps, mail) around 2004-2005 when it was at the same age as Facebook is today. And these products were or turned out to be supportive to their core search business as well. There were another couple of years before we've seen some great technologies from Google which weren't supposed to support their search business. So please, give Facebook couple more years before you judge.

Technical problems that Facebook solves in building and scaling their platform are enough challenging to require and attract the best minds in the industry. Let's see what these people will do when the dust settles a bit.

That said, I'm across the globe from the action and know nothing about these companies culture or attitude. But I still wouldn't judge Facebook yet.
