Maximum PC: Bill Gates is a rock star on so many levels. Yes, he co-founded Microsoft, built his net worth to tens of billions of dollars, and now spends his days doing philanthropy work through the Bill & Melinda Gates Foundation, all of which are admirable in their own right. It would be easy for someone in his position to be an egotistical jerk who's disconnected from the public at large, but instead, this is the same guy who once did the Robot next to Jerry Seinfeld, made us crave churros in another Vista ad, and more recently (as in, yesterday) answered a boatload of questions on Reddit.
