Even as the site asserts its right to own and sell whatever you put there, a new Facebook full-disclosure “game” has arisen: “Memories of us.”

One of my friends posted this:

Here’s the deal…

Leave one memory that you and I had together. It doesn’t matter if you knew me a little or a lot, anything you remember!

Don’t send a message, leave a comment on here. Next, repost this in your notes and see how many people leave a memory about you. It’s actually pretty cool (and funny) to see the responses .

Between this, 25 Things You Didn’t Know about Me, and all the other stuff that people put on Facebook, the site is gradually acquiring the ability to develop pretty sophisticated psychological profiles of individual users. I’m not smart enough to know how all this information could be merged and analyzed, or to what ends it could be put…but nonetheless, it creeps me out.

I keep wondering: Who creates these little games which convince users to voluntarily post intimate information about themselves online? Somehow they just suddenly appear ; there’s no source information at all. We’re supposed to think that they just appear organically, and are user-generated. Highly unlikely. Look at the language above: “It’s actually pretty cool (and funny)…” This is trying too hard; it’s corporate-speak in the guise of casual candor.

Is Facebook writing games to prompt users to upload more personal data about themselves? And if so, why?
