What is celebrity?

Now _there's_ a topic for conversation. What is a celebrity?

According to Dictionary.com, it is a "widely known person".

Fame / renown would seem to be the one absolute necessity then.

By that yardstick, yes Matthew Good is a celebrity.

Unfortunately though, talent or skill are not a prerequisite. Hence we end up with people like that Heung guy from American Idol with his "she bang" routine, who gets on talk shows and gets record deals.
