"Congress is pushing a law that would abandon the Internet's First Amendment -- a principle called "Network neutrality" that prevents companies like AT&T, Verizon and Comcast from deciding which Web sites work best for you -- based on what site pays them the most. Your local library shouldn’t have to outbid Barnes & Noble for the right to have its Web site open quickly on your computer.
Net Neutrality allows everyone to compete on a level playing field and is the reason that the Internet is a force for economic innovation, civic participation and free speech. If the public doesn't speak up now, Congress will cave to a multi-million dollar lobbying campaign by telephone and cable companies that want to decide what you do, where you go, and what you watch online."
