If you have’t seen the new White House government site, I have to say that Obama’s web guys know what they’re doing. Nice feature rotator, inviting color scheme, and easy-to-use links to all the important parts – kudos to the people behind this website.
The coolest part, as mentioned by @allenfuller, is that the inside pages have the oval office walls at the top. It’s almost like you’re sitting behind the desk. Very subtle, but very inviting.
