In your travels across the Web, I'm sure you've experienced Web sites that seem to know you only too well, displaying your name and email address when you visit them and (in some cases) even remembering the pages you visited the last time you were there. Before you allow your paranoia full rein, though, let me tell you that you probably provided the information yourself to the site in some previous visit, and what you see when you return is merely the results of your own actions, reprocessed for a better visitor experience.
