I read up about this after seeing a warning on Craigslist, Facebook and some other sites and I don't like it at all. Simply put, if it passes the internet will not be the same. It will be more targeted for big business's then for the every day user. Giving people business's the right to black list a site and have it shut down if they feel it hinders their sales.
I honestly don't think it should pass because it's taking yet another part of peoples freedom as Americans away.
