Perhaps you should read what cookies can actually store.

It can store a whole lot more than just "number of visits"

I was saying realistically thats as bad as it gets. Anything else that can be tracked can also be tracked server side, and easier too.

The only difference is that cookies are by browser, not by ip. So if you are on an ISP that releases your ip every time you connect to them, you visit a site, disconnect your internet, reconnect, and visit the site again, they are able to tell the two visits came from the same person. If you don't change your IP every visit, there is no difference at all between what can be tracked via cookie, and what can be tracked via ip.

This is true but you have to give that information to the server by hitting it and by having it in your browser, accessible to the server.

So the more you have stored in cookies, the more data can potentially be gleaned from you.
