I wouldn't use the words success or star.  He is something to gawk at.  If he had a show on real TV- I'd never watch it.  But for some reason, on youtube- it's hard to look away.  He is an enigmatic paradox.  However, I don't think on that level he can be a commercial success because his 'character' is too intellectually inaccessible for the masses.  You see the comments on his videos- he's just a fag.  No one gives a fuck.  What matters on TV is the surface.
