I started my present job in August 2001. It is now June 2003. That's 22 months. And in those 22 months, I have moved desks six times. A quick, nonscientific poll of my coworkers reveals that they've moved an average of 1.2 times during those 22 months (n=18).

Tomorrow, I move again. I'm aiming for 10 moves by the time I leave this job in mid-July. :-)
