I'm in.  I've done the 10,000 steps thing for several years.  However, I kinda cheat.  I keep a total of my steps for each week then divide by 7 so I get an average of 10,000/day on a weekly basis.  Somedays I'm over 10,000 so then I can afford to be under on some days.  BTW, this is great for diabetics, it really does do a world of good to keep the blood glucose down.
