".xxx"domain?

Well well, I might be living on another planet (is it called Earth?) but I just discovered that an ".xxx" domain exists!! :o
To some it seems to be an obvisouly serious issue but to some others it just isn't because it means that there will be a way of classifying those websites (cough cough) so that no one will visit them by mistake. Others believe that creating an ".xxx" domain is like an encouragement for the people who make those website so it should be banned. But this argument doesn't seem to be reasonable because those websites existed anyway even before the domain was invented. Personnally, I think it is a good idea because it would classify them harmful webpages so that they can be easily blocked (think about that 12 year old who doesn't understand what the whole issue is... the social/ethical impact).
It's interesting isn't it the ".xxx" domain issue.
