This covers fan pages - anybody know how to do the same for personal pages, in case you feel like snooping on people who are looking you up?<p>But then I see this:<p><a href="http://grownupgeek.com/facebook-forums-whos-been-looking-at-my-prof" rel="nofollow">http://grownupgeek.com/facebook-forums-whos-been-looking-at-...</a><p>Apparently it's against the TOS.
It's only valid for pages built with FBML. So it's good for tabs (sections) but not for the main page itself. The main page is a newsfeed where you just can't put any FBML. So it makes an interesting tool to track subpages but in general it's pretty useless.
Clever idea though.
