Cause their shit is inflammable?
Given that #2 and #3 are substantially less useful in online poker, it's closer to gambling that it is to a "game of skill," particularly for the vast majority of the population with less than stellar probability skills (see the entire population of people playing the lottery).
I disagree. With online poker you can play mutiple tables and don't take nearly as long dealing and handling chips. This makes the number of hands played sky rocket, evening out the effects luck will have on your game. Luck really only effects short term results anyway, make the same decision enough times in the same spot, and your results should converge on expected.
