Rhobite, I think the word "great" may be confusing you.  Sure, what's great for me isn't necessarilly great for you; but when something is great for the many, the qualification becomes objective.  Hellmuth is regularly the chosen televised table, and was invited to this year's tournament of champions event (despite not qualifying) solely for his television appeal.  He currently has logged more minutes on ESPN than any other player.  I'm sorry if you don't know this subject well enough to understand it, but Hellmuth is univerally known and agreed to produce great television.  If I watched Michael Jordan play basketball and thought he was bad, it would not change the fact that he could be objectively described as a "great" basketball player.  Please stick to material that you understand well enough to be able to determine what is subjective and what is not.  I see in your profile that you are interested in photography; I'm sure there are plenty of photography related sections that you could do better work with.
