It doesn't matter if he's good or not, if it's "trials" or not, truth of the matter is that due to his videos (intended or not) he raised a lot of eyebrows and made people look into the sport to attract new riders. Even if it was a total accident; he made the sport a lot more popular, which is good however you look at it.
I for one accidentally stumbled upon one of his videos in 2010, after that I thought it was cool and then dug a little deeper and liked what I saw with other riders and other videos (Damon Watson), the same evening I was practicing the trackstand on the street, and to this day I ride every single day. I don't even like his riding anymore but I'm still thankful I saw that video
