Something I'd have prefered about URL's is a numbering system instead of superdomains, that would allow allocating different sites at the same domain name. For example: * amazon.1 is the index of sites * amazon.123 is Amazon Inc. * amazon.878 is some roof installation company * amazon.111 is a courthouse in Brazil
