I'm a pretty picky user, I send feedback and all that, and I have had such a great experience from beginning to end using RescueTime that I have been telling everyone I can about it. From a time management perspective it is amazing, I can tag the applications I use and sites I visit with things like "work", "email", "news", "social" and then I can also tell it how productive (or non-productive) each tag is.
I love graphs and charts and am a data head, so this has been love love LOVE (!!) at first sight. I can't say enough about it, and I am sure it will only get more amazing as they continue to develop it. Even if it didn't change a bit I think I would use it for a long time, I've never had a tool like this before!
They are in Seattle, just 3 owner/operators.
