You know your 1st Amendment Rights... What about Corporate Censorship?

Every American grows up having some notion of their 1st Amendment rights.  In our country, our freedom of speech is valued (and often hotly contested among those with differing opinions), and anything that smacks of government censorship is an outrage. However, the current reliance on corporations for information and the potential for censorship abuses from the private sector has not yet raised concerns with most Americans .  (Consider for example, the blind trust most of us have in Google's search algorithms and our ironclad assumptions that our search results are a true representation of what is actually available on the Web.)  Check out Tim Wu's opinion piece, in the Nov 14, 2010 Chronicle of Higher education, titled The Future of Free Speech.  Mr. Wu has just written a book called The Rise and Fall of Information Empires.
