Why do so many sites get the itch to set cookies? When you turn cookie notification on in Mozilla, I got a shock at how many sites want to infest your hard drive. My cookperm.txt file has over 4000 entries, for Pete's sake. (Mostly to deny cookies.) I can understand (without liking it very much) cookies set by banner ads, and I completely understand sites where you save personal preferences, but there are some cookies I Just Don't Get.
Then there are the cookie-Nazi sites, those that *require* a cookie for no good reason. For example, at [link|http://www.law.com|www.law.com], you can get to the first page, but any selection you make off that page wants and NEEDS you to allow them to set cookies. "Sorry. You must have cookies enabled to enjoy this site."
I visit the site usually via a reference from [link|http://www.overlawyered.com|www.overlawyered.com]. I have no desire or need to have them provide "better and more personalized service" to me. I don't want them to provide personalized service. Now, likely they aren't doing anything nefarious with stuff stored in their cooky(ies), but the thought of providing lawyers any more information about me than they absolutely need is a bit chilling, as well.
(That site also does the (in)famous "back arrow takeover" on its "you have to have cookies enabled" page, which doesn't do much to impove my attitude toward the site.)
