This reminds me of something I started many years ago (2007-03-10) I wanted to track my mood throughout the day and eventually over years to see how different events and times of the year effected me, does anyone know of anything that exists for that now?
Something we put together back in '98 and one of the guys still keeps it running: http://www.imood.com It's not what you would call "well designed", but it was fun back in the day and managed to get a bunch of users back then.
(only slightly related, please forgive me)
