It is worth having a look at the new look White House web site. It shows how well prepared the Obama administration is. At 12.01 yesterday, two minutes before Obama was actually "sworn in", the website was switched completely.
It is possible that they are trying to be a bit too clever though. On the website we are told that "President Barack Obama, Vice President Joe Biden, and their families spent the day (Martin Luther King Jr Day) honoring the memory of Martin Luther King Jr. by serving others."
One slight snag.
Martin Luther King Jr. Day was on January 19th this year.
Barack Obama didn't become President until January 20th.
