EOP - Blog Post - Change has come to WhiteHouse.gov
Welcome to the new WhiteHouse.gov.
I'm Macon Phillips, the Director of New Media for the White House and one of the people who will be contributing to the blog.
… Our initial new media efforts will center around three priorities:
Communication -- Americans are eager for information about the state of the economy, national security and a host of other issues. This site will feature timely and in-depth content meant to keep everyone up-to-date and educated…Transparency – .. The President's executive orders and proclamations will be published for everyone to review, and that’s just the beginning of our efforts to provide a window for all Americans into the business of the government. You can also learn about some of the senior leadership in the new administration and about the President’s policy priorities.
Participation – …we will publish all non-emergency legislation to the website for five days, and allow the public to review and comment before the President signs it.We'd also like to hear from you -- what sort of things would you find valuable from WhiteHouse.gov? If you have an idea, use this form to let us know…
