Maybe I don't get it. I'd like to see your data for point 1. Radiohead decided not to repeat their experiment.
As far as an 'inordinate amount of attention', he got buzz because of the model and not the product (which people are happy with). Do you think the next person of similar stature will get similar attention? The second? The twentieth?
That attention helped drive sales. What will it be without it?
Sidenote: I make a comfortable living via online content. I know it can be done. The unanswered question is a breakout success like C.K.'s possible without big media help?
