There have been a number of blogs posted on ActiveRain (on Tammy, Fred and Katerina's blogs to name three) recently talking about the Stop Online Priacy Act (SOPA) and the Protect Intellectual Property Act (PIPA).
Both are well intentioned, but poorly crafted. Both proposed acts in Congress would increase the ability for the government to censor free speech. Both bills give the courts and the government significant power to shut down a web site if trademarked or copyrighted material is found on a web site.
This would make running a web site like ActiveRain that has user generated content like say blogs nearly impossible.
Today a large number of websites like Wikipedia and Google are showing their lack of support for SOPA and PIPA by "blacking out" in one way or another.
Learn about SOPA and PIPA on your own and if you decide sign a petition, visit Fight for the Future, and contact your local congressmen. Each of these web sites will help you find who you should be speaking with.
