Thanks all! I think our concern and enthusiasm for Microsoft and other companies is the impetus of the development of the internet business. I read in some forums of my country suggesting that live.com mail is becoming extremely hot and popular because of the "crazy" registration flood of new accounts. Personally I have been using hotmail since the 90's so I have personal attachment to it although I also possess and enjoy other emails too. I think the charm & appeal of a email to users is not how short and cool the usernames are, but how nice it functions to service. After this idea I think registration of live accounts is not at all a big problem for Microsoft as long as its service is good. Anyway these accounts are free and it does not matter to Microsoft who are using it; they cannot get any cent from users' identities but they can get a wealth from the amount of user number. The most important thing for MS is dealing with PR with its free users to keep a large herd. We can see people using hotmail and msn emails with super long usernames, that's a proof that people will use live mail even if they can only get long usernames if the service is nice. Anyway good luck to Microsoft and its rivals because their competition is making life easier. Thanks to them all!
