My idea was never just to hide a happiness charting application somewhere on the web to be forgotten about. That's never gonna work. Not even with Facebook integration.

No, to keep this data fresh, it needs multichannel access; it needs to ask you for data.

About a year ago I first built a web application that periodically enquired after my happiness. It is a very strange feeling to have a message like that pop up in your IM client. Even when I'd written the code to make it talk to me in a nearby terminal window, it still sorta gave me a warm feeling.

I'm used to being asked how I am. But the only answers I can really legitimately offer are 'fine' or 'great'. This Facebook app is a much more scientific approach. I want a record of my mood, I want to be able to track and remember what made me happy, so even if I can't remember the feeling, I can't deny that it happened..

I still haven't made it past 6/10 for the whole time I've been working on it but - well - I'm sure I will sooner or later.

Go and try it out for yourself at Facebook: Mood Tracker.
