ooooh, they can tell what windowblind I use? Next it'll be what I et for breakfast! Oh the humanity!
WOM, I know for web based stuff, the browser gives up the user agent which provides the OS, browser used, and sometimes the ISP is coded there too. That can be changed by a minor registry hack for those who don't want to give out that info. But then some websites won't work with goofy user agents that some people come up with.
Anyway, I was just wondering where the stats came from and how they were gathered.
