Dangers of Becoming a Web Celebrity

I was talking with a friend the other day who was telling me how cool it would be to work for one of these web celebrities. Then I peed in their cheerios telling them I don't know of many celebrities who have ever done many successful businesses. There have been many successful business people who turn into a web celebrity and then their business sense goes in the shitter. The truth is its VERY rare that any celebrity has much business sense including former successful people who turn into celebrities. The only exception I can think of is Donald Trump. He has managed to go on to do even bigger things after becoming a celebrity. I am not going to call out certain people but search a round a bit for .com zillionaires who became famous then have not done anything since... At some point being a celebrity becomes your business... that scares me.
