I think he's the most popular YouTube currently, or close to it if not. You can't get around without hearing about him occasionally. The biggest thing I know about him is he does charity videos that he films where he gives poor people a little bit of money. It's pretty obvious to me it's just exploitation to improve his image, and also he makes far more money off the video than he gives away. Clearly he isn't doing it because it's a good thing, yet somehow people call him a good person because of it.
