It's amazing what can be tracked with cookies, including across sites. There 
was an article, in The Australian I think, a few years ago describing 
information PBL had accumulated through cookies.

How many times do you go to a website and get cookie requests from several? 
How hard would it be to match cookies across domains? Information readily 
available to seach site supplying a document includes referrer, client IP 
address, time. Say I go to
 http://www.example.com/
which sets a cookie and includes a document from http://tracker.example.com/, 
and passes the cookie data (or a token identifying it so as to hide what's 
going on), and tracker also sets a cookie.

Then I go to 
 http://shop.example.com/
and it  includes a document from http://tracker.example.com.
Cannot tracker match my two visits, and maybe record my credit card detaisl 
"for my greater convenience>"

I tend to allow session cookies, but rarely permanent cookies.

I also tend to use divers browsers and computers which surely must help 
confuse things.
