This is all true. What I meant was that not that many users disable JavaScript which makes those users stand out more. It's easy to test from a server--just serve a JS file that would make an AJAX call or load an image with a unique ID, and if it doesn't hear back then the user probably has JS disabled. I don't have any statistics on how many users disable JavaScript so I don't know how much of a problem it is. Although I'd imagine a sizeable number of Tor Browser Bundle users would disable JavaScript. Andrew
