Besides his day job at the Cato Institute, Jim Harper is the creative force behind WashingtonWatch.com, which places a value on changes to future federal spending, taxes, or regulation. The goal of the site is to convey the significance to average Americans — in dollars and cents — of proposed changes to the nation’s policies. Jim’s new widget allows bloggers to show the current state on pending legislation. It allows individuals to comment on the bill, and to even vote yea or nay on the legislation. It’s very cool.
