Something is rotten in Congress.
I don't know much, but many of the major blogging platforms and a lot of high-profile websites are pleading for folks to make their voices heard about possible new legislation that will allow entertainment companies to essentially censor the internet (protecting the corporations copyright over individual free speech, is what I understand to be the essence). Here's a video:
PROTECT IP Act Breaks The Internet from Fight for the Future on Vimeo.
American Censorship Day
Fred Wilson: Architecture of the Internet
BoingBoing: Stop SOPA, Save the Internet
EFF: Hollywood Finally Gets Chance to Break Internet
The legislation itself: Stop Online Piracy Act (SOPA)
Ars Technica: House makes bad internet censorship bill worse
and there's plenty more if you dig around on any of those sites. but mostly I think aggregate clicks and presence from the collective voice of the internet is needed, so spread the word. use the American Censorship Day link, or Tumblr's Protect the Net page.
