I was reading about Bill Gates joining Twitter (http://twitter.com/billgates) and wonder what's the process for having a verified account. How do they evaluate that someone is known enough to have a verified account? Is it twitter that communicates with the account holder or he has to make a request to twitter? How do they verify that it's the real person behind the account (probably with a special CNAME but maybe not?)
