I have a stat counter on my blog. It tags posters and -- if I want to check -- gives their ISP, OS, browser, location to the nearest node; it offers a map, how many times they've visited, how long they stayed, and all sorts of other things: where they came from, the path they used, search engines. I don't put this info up, but I can access it.
Since anybody with a web page or blog can use this kind of program, and since anybody who surfs leaves tracks unless they use a masking program like Vidalia's onion and Tor, or some commercial service that misdirects, the idea of Big Brother watching you isn't much of a surprise. I was just wondering why anybody bothered to stick up notice.
