Follow President Barack Obama through the day via Twitter using Tumblr. (Tumblr is a conversational-style real-time platform, sort of a scrapbook for the historic day.)
From the Official Presidential Inaugural Committee Twitter log, "We're using Tumblr to create a dedicated feed of Obama-Biden Inaugural content for the blog today http://bit.ly/2ob5EQ"
See http://twitter.com/obamainaugural for other real-time communications called "tweets" and see how the potential of communication technology is deployed by the incoming staff and President.
