In 1929 as Governor of New York, Franklin D. Roosevelt started using radio broadcast to appeal to his voters to help pass legislation that he was working on in congress. He later continued this practice while president of the USA. These talks were later coined "Fireside chats." FDR used the technology most accepted by his constituents to further his cause.
Fast forward almost 80 years (four score for you history buffs) our new President-Elect has chosen YouTube to host his weekly "radio" talk. No matter what your political affiliations are; we should be encouraged by President-Elect Obama's use of technology. He is using the most pervasive means to distribute his his platform.
In addition, YouTube also allows comments, so we are all free to voice our opinions if we disagree.
