Google should be careful here. I have been part of teams where managers go ahead and make 'diverse' hires just to fudge the numbers despite getting an explicit 'no' from the engineers who interviewed them. These hires were always terrible and bring productivity down big time. I see no difference between this and caste based reservation in countries like India (http://en.wikipedia.org/wiki/Reservation_in_India http://en.wikipedia.org/wiki/Reservation_in_India). In states like Tamil nadu (India) only 30% of seats are available to brahmins. Note that 30% is open quota - everyone competes for those 30%. Even the people for whom things seats were reserved for already. Diversifying the work force should never be a goal by itself.
