From the article:
"If you observe him closely, you will find that a geek approaches non-computer avocations in a fanatical way and always with the certainty (in keeping with an outsized opinion of himself) that he can master any subject with a dilettante's effort. In fact that seems to be the whole point of the rare excursion into non-computerized activity. Once his shallow sense of mastery is satisfied he ceases to progress in the avocation because really hard work bores him.
This is the geek as you might find him on Slashdot and in other forums arguing about Firefox or Linux or whatever his latest petty obsession is, and as I find him walking past my office day-in and day-out acting like a child. I tell you these people make feminists seem charming.
