Can you help me understand the contempt you have for the Zynga games? I don't play, myself, but I do understand that the games exploit (negative? compulsive?) psychology, and they've used unethical business strategies.
But who cares? After all, it's unlikely the next Vonnegut is going to spend his time playing MafiaWars instead of writing "Slaughterhouse Five" or anything.
I am reminded of the aphorism, "Time you've enjoyed wasting is not wasted time."
