IMO, FB is moving in the right direction: adding gates (windows?) to the walled garden. What I would really love to see, and maybe this capability already exists, is to add a widget to any webpage (my website, blog, or even YC profile) that would list my FB info (as little or as much as I choose) to others. The amount of info would vary depending on whether the viewer of the widget was logged in to FB, and someone I've friended.
They have (or had, not sure if it's still there) something called a badge that you can put on your site. I don't think it varies based on someone logged into facebook (don't really see this as possible, since my site cannot access FB cookies).
I for one welcome our public search... oh shit! wrong news site...
Man, whoever downmodded me... it was just a lame attempt to be funny...
