Perhaps I should put it another way: an attempt to clarify, if I may.
I find a discussion about the internet culture of particular players to be, at best, mere suggestion. The anonymity of the boards themselves (gamer tags nonwithstanding) mean that each person has no difficulty in molding thier personalities to the boards they post in an creating what appears to be a "trend" where there really may only be miming.
Now, if we were to take the same scrutiny to the tournament level, we would see something completely different-- Not only becuase there is a distinct change in environment, but also a distinct change in community.
My experience, in the few tournaments I've been too, has been that the community of SSBB at competition is seriously lacking. I've come across a few players who, outside of competition, were sociable and amiable. Most, no matter the character, had little to say to anyone. Viewing an opposing player as an opponent is natural. Shutting out friendly or social action is not-- and it's awkward to see players click into two's or three's and then find some kind of pleasure in avoiding everyone else.
Then again, tournements 'round here see a lot of snake and metaknight lovers, so maybe that's tjust them ;D
