Techdirt is reporting that the .xxx top level domain (TLD) is up for consideration again, but cites it's own 2004 article on the subject that forcing porn sites to migrate there would be a bad idea because the definition of porn can be subjective and defined differently between different people.

Phooey. At the very least it would force most porn sites (the "I know it when I see it" variety) to that TLD. I mean, most people don't disagree that the content found in adult bookstores and on the adult magazine rack qualify as x-rated material. I don't see a whole lot of people trying to qualify adult material as art these days.
