Agreed with Duke there, there's no such thing as a smart diver or a dumb diver. If you want to name the biggest divers, I suggest you look at the teams first, Man U, the consistent "performers" are Ronaldo and would you believe it, Rooney! Many would not agree, but if you watch him game properly, despite his stocky build, Ronney is one of the biggest diver, it's just that he is able to deceive the referee more because of his "craftiness in the art".
Chelsea, on the other hand, has a few good ones there, Drogba, J Cole, Robben, SWP (when he plays). Arsenal have the likes of Hleb, Rosicky, Van Piersie, Fabregas, almost everyone else.
Liverpool with Gerrard, Garcia, Pennant.
The thing is this, diving existed long before 1992, when the premier league is formed. The thing is that with more cameras scrutinising the movement of players, it is easier to pick up diving with the slow mo replays and all that. So, it would be pretty dumb on the players part to blatantly dive if there's no contact and try to make a fool of themselves.
If you ask me, if there's contact and you make a meal out of it, then it's diving. Whether it gets you a penalty, you opponent sent off or anything, it is cheating. Oh yeah, I don't buy the "intent" crap either. Thoughts and actions are 2 different thing.

You talking about me mate? Thanks for the compliment mate.

None taken mate, in fact I would see it as a compliment. Hehehe...
