I had an idea for a Facebook application in the pub last night, but I’m not sure if it already exists.  I suspect not, for possibly obvious reasons.  Perhaps someone might let me know?

It’s really simple.  I’d like there to be an application which tells me which of my friends have spent the most time looking at my Facebook profile.  And perhaps which bits of it they spent most time looking at.  Like pictures.  That’d be interesting. 

Of course, I’d also like to be the only person in the world allowed to load it.  Or I’d like to at least be able to bar selected friends from loading it.  Particularly the lookers.
