First, Minority Leader John Boehner has a twitter badge up on his Republican Leader website. This allows him to post status updates on his whereabouts to a very specific degree. While it appears to only have been updated once (in reference to the House vote counting dustup), he should be applauded for engaging with technology that has such immense potential for facilitating public disclosure. (The only other search results for “site:www.house.gov twitter” are for George Miller and the Republican Study Committee.)
Second, via Speaker Pelosi’s blog The Gavel, Rep. George Miller (Chair of the Committee on Education and Labor) has posted a map of workplace deaths in the US, apparently mapping ten percent of workplace deaths from 2007. As google maps and other mashups get easier to manipulate and embed, we should expect to see this sort of data presentation crop up more often.

Imagine if all federal agencies had APIs that encouraged this sort of creative statistical presentation, and all members of Congress had the staff and desire to start making more of what they do meaningfully public.
