Further to previous notes on Steven Johnson's Everything bad is good for you, this Sunday's Observer had an article by the man himself entitled Viva virtuality.
Aleks is also talking about the article over on our Gamesblog, but it encapsulates what I thought was the best soundbite quote from the book:
"The dirty little secret of gaming is how much time you spend not having fun."
I'm sure anyone who's spent hours playing any number of frustrating games can agree on that; but it's amazing how many people who don't play games imagine that they're simply mindless pleasure-inducers.
