We're currently revisiting the project and working on finishing up the API. Yesterday a thought occurred to us that we couldn't answer: Will this data be interesting or useful to anyone other than ourselves?
We would love to get the thoughts of the HN crowd figuring that if the data isn't interesting to anyone here it might not be interesting to anyone :)
You can see the data in action here:

Thanks for the feedback!
