One of the reasons that IE marketshare is so hard to measure is that it depends on whether business users visit the site. You can see this if you can get data that isn't filtered. The only public data I know like that is Clicky [1]. Note the sawtooth wave caused by users who use IE7/8 (and now IE9) during the week but some other browser during the weekend. So IE8 marketshare is almost 2x higher during the week than on weekends. http://clicky.com/marketshare/global/web-browsers/internet-explorer/ http://clicky.com/marketshare/global/web-browsers/internet-e...
