A couple of months ago, ICANN, the organization responsible for Internet addresses, approved an .xxx domain, which is supposed to be “porn-friendly.” The idea is to encourage porners to go to a single domain so they can easily be blocked by those who don’t want porn to be accessed on their computers.
Just before it was going to put into place, a number of governments, including, but not limited to the U.S. government, raised objections to the immediate implementation of .xxx, and wanted to talk about it some more.
