I actually think a celebrity like Kim Kardashian might get off to a slow start, as the current user base might not really be interested in her blogs about shoes and make-up.

However, once she starts promoting her Steemit account to her fanbase, she could bring an entirely new demographic to this platform. She could go on reality tv shopping sprees buying shoes, purses, or even cars with her Steemit income. She would promote her Steemit account like she promoted her silly iPhone game.

I think celebrities would bring in new demographics that would only grow the size of the pool making it impossible to squeeze anyone out!
