As far as knowing the rules and etiquette, you have a point and a very good one. The only thing I can think of as being an advantage to the on-line player is that if you have become good at the game it is because you understand the very basics of the game, the odds, the right hands to play etc... I think the added advantage of being able to see your opponents could only help you, at least a little.
