@Compworld - You're only listening to what you read on some forum somewhere and not the truth. Are you aware that Bing also collects data when you do a search with that? Yahoo, too? Are you aware that MSN does and your local newspaper? Are you concerned with what they do with your visiting habits?
Visit any of my clients pages and I know where you came from and where you went. I know your IP so I can narrow down to where you live. I know what you clicked on, how long you stayed, what OS and browser you use; your screen resolution and more.
