For the life of me, I never have fully understood the human compulsion to fill out forms containing their personal data on a computer. If I walked up to a random person on the street with a form asking for their personal data, they’d probably think I was up to something unsavory (like signing them up for a credit card), and tell me to shove off. You put the same person on Facebook, and it wouldn’t surprise me if at least a good portion of their extended profile information is filled in. What benefit does this give anyone but Facebook and their demographic-engine? You know, aside from thoughtfully tailored ads for the user’s pleasure.
