Great job, Nils. I didn't know Google doubles the reward if it goes to charity.
I wonder why Microsoft doesn't have a similar program. Hotmail just got hacked pretty bad[1], and the hackers were selling the vulnerability for chump change in forums[2]. What if they had an incentive to report it to Microsoft instead?
