Tell me, downvoter, what Bill Gates and Warren Buffet have done that will be more memorable than perhaps in a few years having wiped out malaria? Windows Vista? The Zune? Buying Gillette and Geico? Downvotes contribute nothing to a discussion, and without commentary they serve little purpose, save to inform the downvotee that you have something against what they said yet felt disinclined to share it..
