Obama is strongly for net neutrality. He spoke at Google a little while back and said it would be one of his first things he does.

McCain is against it. He is also for regulating social networking sites to an extreme. You would be required to report any CP and some forms of "obscenity". If not, you go to jail and get fined. Makes it easy to put your competitor out of biz pretty quick. And to shut down almost any adult site under the guise of obscenity.

And lets not forget that McCain wants strict constructionist judges while Obama wants more liberal ones. Strict constructionist ones are the ones that believe that porn is not safe under the First Amendment.
From a sheer internet standpoint, especially in adult, Obama crushes McCain. But some people have other reasons for voting.
