I don't use Youtube as research medium, I just happen to like the action videos that Freddie Wong put's together. if you ever take a look at his video's, they are funny, action packed and the CGI are pretty good as well.
But I don't use Youtube for as any thing more then entertainment, and maybe to watch reviews on different gun. like those on Redwolf and Evike.
