It would be nice to have a form to enter the data with: http://forms.google.com/
Author here. I wonder if you are referring to the form to enter the data? The link to the form is https://docs.google.com/forms/d/1J99v2E-jYM8JlIUPvTPfyc5v_pt... (this is actually the link that this HN post is linked to :) you might have missed it).
Thanks a lot for your interest.
