Hello,
I've noticed that .BZ domains are rarely mentioned on this forum. I own a few and I disagree with people who think that .BZ domains are useless. I think they are underrated now but are bound to increase in value in a few years time. And for someone looking for a SEO boost to his site, a .bz domain is an ideal way to get a keyword rich address without shelling thousands for a .com.
Moreover I believe that .bz are superior to say .ws or .mx because english is the official language of Belize.

What's everyone's opinion on .bz?

I also co-own BZdomains.BZ, a '.bz domains fan-page', if you will. There is also a section where you can advertise your .bz domains for free ( contact admin on admin[at]bzdomains.bz. )
