"Don't Let Congress Ruin the Internet
Right now Congress is pushing a law that would abandon the First Amendment of the Internet -- a principle called "network neutrality" that preserves the free and open Internet. Congress needs to hear from you today or they will hand over control of what you do online to companies like AT&T, Verizon and Comcast.

Politicians are trading favors for campaign donations from these companies. They're being wooed by people like AT&T's CEO, who says "the Internet can't be free." Sign this petition to tell your elected representatives to protect Internet freedom now."

While this organization seems really bad at explaining what is happening, I think it is worth 5 minutes to send an email to reps and sens. Of course, what they are proposing is that it will be legal for gateway companies like AT&T and Comcast to take money in exchange for faster load times. That is, Amazon could pay for the routing to its sites to be quicker than those of independent book stores or whatever. BTW I had a friend who wrote about this possibility some time ago. He blames CISCO routers.
