I've been tinkering with Mood Tracker again (my Facebook app - try it here http://www.new.facebook.com/apps/application.php?id=25355222452 )

I've made it so you can edit your reports and added in some new charts. Personally, I'm finding it rather instructive. It's nice to have some hard scientific data to hand when making decisions about how to change your life. You should try it. Prioritising, of course, the activation of the IM bot 'Auntie' who will make sure you keep your data fresh!
