And on facebook, briefly, really just checking on the co-workers status on days off, when I see that one of the co-workers, a weekender, is playing farmville.

I see this because she's online all day, the game sends out alerts to all her friends telling them what she needs - "So and so needs a -----" or "So and so needs a -------? Do you have one to give her?". 

It's inane. Entirely. I want to message her the same farmville messages that keep appearing on my facebook telling her that "So and so needs a life....", but probably that wouldn't go down so well.
