Right, but the theory (which I'm arguing against, see above), is that if economic rewards are grafted on to the social side then people will become more open so that they can become more economically successful. Youtube comments and today's FB aren't economic - there are few incentives against bubbling yourself beyond personal gratification.
Sorry, poor wording on my part. I didn't mean to imply you were supporting that theory, I had never heard it before and was just shocked that _anyone_ believes it.
