Despite the hoorahing by libertarians, this will hurt the internet. A lot of families eschew internet access because of the porn. It's not just available, it's in your face. It's shoved in front of the most innocent surfer. Nobody has found an effective way to stop it, because the people who created it and run it think it should be free. I know that it makes a lot of money, and is the basis of a lot of much of the growth of the Web. But I also know families who won't allow it in their homes. The computer companies and isps have saturated the market. Future growth will depend on finding a way to control access to porn.
