Good work Kimoto, however, why don't you keep the old domain with a forward to one of the new ones?
There was a discussion on IRC about domain names with the "co.nz" extension being misread as "cons". Many websites are now incorporating the TLD into the overall name, for example "Hashco.ws" the mining pool.
The number of people that agreed was surprising, I find the idea preposterous that someone would not trust a website and get the wrong idea because of the domain name extension, but it was pointed out that many of the visitors will be from foreign countries.
In a world where different cultures and superstitions affect perception, all things need to be considered. Many people will not purchase something because it has an unlucky aspect, in their opinion. They may avoid buying a house because it has an unlucky number on the letterbox.
So in the end the participants in the IRC channel agreed that
no websites (with an international outlook) should use the "co.nz" domain name extension. This happened in December last year, at the time I was speechless because "for the most part" I ignore the TLD, but it is undeniable that "some people" will base their opinions on the domain name extension.
Forwarding the old domain names is not desirable because it does not force a change, many people will continue to link to the old addresses if they continue to work.
Hope this clears up some of the confusion.
