The first changes took place immediately after President Obama was officially in power: The official White House Blog was launched. It’s like a "regular" blog. It has all the components of one--except commenting has not been enabled. :)
The first order President Obama signed off on is a post on the blog. The "filter" that is so often referred to between the party in power and the mainstream media has officially been removed. This president can speak directly to those of us with Internet access, and will do so via the presidential blog and YouTube.
President Obama is already an Internet star; check out this ancient footage from four years ago when Ciroc Obama, more commonly known as Diddy or Sean Combs, met Barack Obama for the first time.
