Try configuring your browser to ask for your permission every time a cookie needs to be stored. Some websites have 4-5 cookies and clicking "accept" (or "deny") several times over for a site is just unusable.
I use the Cookie Monster addon for Firefox. it provides a similar interface to that provided by NoScript. It blocks cookies by default, and lets you permanently/temporarily accept full cookies/session cookies, on a per domain basis.
I can use news.ycombinator.com because the first time I came to this site after installing Cookie Monster, I set it to accept session cookies from ycombinator.com, and to permanently remember that setting. I don't need to let ycombinator set long lived cookies, and I certainly don't need to let clickpass.com set a cookie on my computer when I visit the news.ycombinator.com login page.
