I have mentioned that this site will be participating in American Censorship Day. There are 2 different bills, and both are just as bad.
PROTECT IP Act, or (Preventing Real Online Threats to Economic Creativity and Theft of Intellectual Property Act of 2011), United States Senate Bill S.968. A similar House version of the bill, the Stop Online Piracy Act (SOPA) was introduced on October 26, 2011. I have linked both bills to their Wikipedia pages.
Even if you do not have a website or a blog, YOU can take action by writing, tweeting or emailing your Congressman.
