This has a bunch of gopro HD footage in it. I think it's a nice touch.
As with anything photography/videography it's all about the eye of the person mounting the camera. Not so much about the equipment attached. Having a day on the mountain with the camera pointed at your ski tips all day isn't exactly appealing to every eye. You may thing that's awesome, but I can't say it's worth posting on the web. The problem is the people clicking the upload button more than it is taking footage on the mountain or on the river.
Millions of photos post on Flickr every day, we don't bitch about them. I know a lot of shitty photographers including myself. I appreciate their aspirations to excel, but their just as guilty as the youtube uploader with a gopro.
I don't have kids. But if I had some little ones that wanted to see daddy do this stuff when I'm old and grey, I'd be glad I had the footage. Albeit not on youtube...
Edit... wait, who am I kidding, I'm not quitting when I'm old and grey.
