I think the difference is that YouTube /pays these people/. It's almost an employer/employee relationship. YouTube generates revenue, youtube shares that revenue, contributors with tons of views are making money directly from YT. This is simply not the same as Twitter, etc. Twitter may make money off of eyeballs. I may somehow make money by becoming twitter famous. But my money is not coming as a share of twitter revenue. The incentives are all screwed up. YT benefits financially the more 'shocking' my vid can be, and I benefit financially if YT does.
