It is not always completely trivial to identify individual visitors? That is a very low standard.
I don't describe it as "not completely trivial" because I think it's some sort of laudable standard, but because you are implying that it is a completely trivial task.
Using information which in all likelihood is known to no-one else on this site but you, you've found a reliable method of uniquely identifying yourself. If you hadn't published it, the amount of effort required to identify you would probably be enough of an obstacle to deter anyone with a sudden hankering to investigate your recent LW browsing history from doing so.
My original comm...
I have just realized that sitemeter has the following data published about my visit, in a searchable and browsable format:
en-us
Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.2.13) Gecko/20101203 Firefox/3.6.13 GTB7.1
I am not a privacy geek, but isn't this a bit too extensive? By the way, I am not from Etyek, Hungary, I am from Budapest, Hungary. Etyek is a very small village, so if sitemeter consistently identifies me as someone from Etyek, then it will be even easier to track my lesswrong browsing habits. It is very easy even without that.
