According to this article,

the Supreme Court just declined to hear a case arguing that the Miller test and local community standards for obscenity are unconstitutional and impose an undue burden on the creators of art or media.

The attorney for the plaintiff believes that the refusal was more about politics than constitutional law. What a surprise.

On the one hand, I'd be in favor of a national standard, as pretty much all other countries have. On the other hand, I'm not sure I'd want some of the new batch of idealogues making those decisions.
