Let me start by saying that I'm a really picky reader. I don't read alot of other people's editorials because I have so much reading to do during the day that it loses it's appeal. However, I generally tend to read what's on Gamasutra. If only because it's generally really well written.
Now, to my point. David Sirlin has written an editorial named World of Warcraft Teaches the Wrong Things. Being a staunch defender of my current game, I wanted to read this to find the flaws, prove him wrong. No such luck. He has many valid points in this article and I highly encourage you to read them.
