Lunchtime poll: Is FarmVille, Facebook games addictive?

After reporting the news that a FarmVille-addicted mother shook her child to death for interrupting her game, we couldn't help but look back at recent headlines and studies that say FarmVille and other Facebook games are designed to be addictive and that people who are susceptible to addiction are making these games their drugs of choice. We want to hear your take: Are these games addictive or not? Vote in our lunchtime poll.
