It's an interesting discussion that's becoming more and more prevalent as T.J. Cloutier and Doyle Brunson who bring a certain amount of class to the game. There are also some wonderfully analytical minds in poker with guys like Daniel Negreanu and Chris "Jesus" Ferguson. And let's not forget the ladies - Jennifer Harman, Clonie Gowen and Cyndy Violette are just a few of the talented females that play.
Included above are some very interesting archetypes, and the thing about poker is you never quite know who is going to be at the table. In other words, any of the above could face each other, and when they do, you don't know what to expect.
To make things even more interesting there's another type of player that frequents the tables - you. Well maybe not exactly you, but guys like Greg Raymer and Chris Moneymaker have shown that average Joes can climb to the top of the poker echelon. If that's not a reason to take an interest in professional poker, I don't know what is.
Maybe the reason average people are starting to make poker players into celebrities is that when and if they get to the top, they'll want that kind of status too.
