The idea: If the text "www.whitehouse.gov" would be visible on the podium in front of the microphones on all occasions when the President speaks, more and more of those folks would visit the powerful website of the white house whom would have never thought of doing so before.
Every time President Obama speaks, millions of people watch him (not always the same millions).
The TV is the best advertising venue, why not "utilize" it any time the President speaks from the White House? (Or even from the library of Congress if it's OK by any means).
Why is this idea important?
Because, the website of the White House can be and is so powerful in communicating with the American people (First time in History!!!).
I think, it would be even better if President Obama would take the opportunity once and mention the website of the White House in one of his speeches, talk about the different ways the American people can communicate with the White House and actively participate in building the future.
