Next time you're filling out a registration form on the Web, try this experiment. Enter only your last name and ZIP code (let's assume you're a U.S. resident), then click Submit. The form's handler will complain about a bunch of missing fields, including address, city, state, country, and phone number. Now visit Google and type a query based on this construction: phonebook: LastName, ZipCode. If you're Jon Udell in Keene, N.H., the missing fields will pop right up.
