What would be useful, not that I have looked into this to much to know that it isn't possible. Would be to group the time spent on HN with the time spent on anything linked from HN. It's hard to know how much time I spend on HN/HN articles. Great tool though, RescueTime and DropBox are the two ycombinator companies which I could instantly see a use for in my everyday work.
