I play WoW 10-15 hours a week with the wife, in-laws, and other IRL friends. It's a great family activity and helps me keep in touch with friends from high school that now live hundreds of miles away.

I also put in ~50 hours/week into my job at a startup, and have been told I write good code. I'd wager I'm not a bad employee.

I'd agree that WoW addicts wouldn't make great employees. However, there's a huge difference between a WoW addict and a WoW player, please don't lump us together.
