I can understand why this comes as a shock to some; it may be difficult to accept that another person doing his 9-5 job can bring so much value to a company. I always suspected such value creators exist (Jobs would be one).
So good for him for delivering, and good for Google for acknowledging and compensating accordingly. And good for me too; I'm taking my first steps as an advertiser with Google and I'm really liking what I'm finding so far.
