What's interesting in this list is that Porn Industry gets its own share of the Internet thro the xxx suffix. The reason for having a seperate suffix for adult-oriented sites is that this will allow greater protection for children, because filters will easily be able to exclude any sites with xxx suffix. I don't if it really can help protect children as these companies will have their domain mirrors in other suffixed addresses as well.
Soon, we might have a seperate domain for ads and spams - with the claim that filters can filter them better!!!
