The entire article is set up to emphasize the way that anyone should be able to tell she's a gamer from the way she holds her hands on the keyboard

That's kind of egotistical. I have played computer games since I was a kid and WASD is natural for me too, but I don't think of myself as 'a gamer' because I probably devote less than 1 hour/week to games.

A bit unrelated to the article: first thing I do on any game is change WASD to arrow keys (and swap the mouse to the left). Without much thinking I would assume people who don't do that are at most casual gamers. :) I definitely wouldn't see somebody going for WASD and think "this must be a serious gamer".
