Pointless limitations
What does it matter what the name of the TLD is? Why are we restricted to a limited list of TLDs? Oh yes, that's right. Introduce an artificial shortage to boost prices. Effing con all of it. There is no reason why you shouldn't be able to register any reasonable length TLD since all it requires is an entry in the Top Level DNS because your domain name is just a pointer to an IP Address. So, why not just allow any TLD up to say 8 characters and allow anyone to register them so long as they are not obscene, illegal, or insulting. Why do ICONN get to decide which TLDs are allowed or not? Why can't we have TheRegister.England or TheRegister.Wales or TheRegister.Scotland? (sorry Northern Ireland, your name is just too long! <LOL>). As for Nominet, they seem to be turning into just as much of a ripoff/con as Public Interest Registry's recent attempts to sell off the .ORG registry for profit.
