After checking latest Make magazine I've joined the forum.
Not just out of interest, but I have also created a tool called "Kronokraktor".
It is a personal time tracking tool (currently only a web tool - iPhone app is in the making).
It is a tool to track "where your day has gone".
Currently it is in private beta, but you can see how it works by checking the video at http://www.kronokraktor.com.
