This is sort of a generalization of URLminder. The idea is that you pick a public URL to point us to, and then give a regular expression, the first match will be entered as a number on your beeminder goal.

Your Beeminder pledge keeps your doing the thing, and we keep recording the changes in that number.

Stay on the right side of the bright red line and your money is safe.
