I thought it was pretty awesome.
I don't remember the youtube comments being that negative either, but then again just about the only site I ever got into early was facebook because I was on it when you still had to be a college student. Myspace, youtube, twitter (which I still haven't got on) I got on way later than everybody else.
So the rough comments might've been over on youtube already by the time I got there.
Of course, I don't know what was said to him in person and I know people can be douches. So good on him for being successful and supportive of other people who might be on their own and struggling atm.
