I ran across this page - Legislative Documents in XML at the United States House of Representatives: "The purpose of this website is to provide information about the ongoing work of the U.S. House of Representatives in relation to the eXtensible Markup Language" - and thought the host name was very cool - xml.house.gov.
This page has pointers to DTDs and schemas for the governmental processes involved with making and amending laws. So the next time we need to form a more perfect union, we've got this going for us.
And that page led to this page of a summary of floor proceedings of the US House of Representatives. It reads like a blog, only with less detail and there is no RSS feed.
