IE6 usage

Just was looking at analytics for a major site my agency works on. The amazing thing was the IE6 usage looked like a heartbeat. Steadily decreasing (thank god) but peaking during the week and dropping on the weekends (IE 7 & 8 showed similar increases during the weekend). I guess the feeling that it is just big corporations forcing people to stay on IE6 (and so at work) is proven out here.

This behavior was consistent and periodic over the past several months. Interestingly, Firefox showed none of this fluctuation. I guess people being forced to use IE6 at work, aren't switching to Firefox at home.
