I have to say again that Registan is far and away my favorite Central Asia blog. It has a variety of people commenting and posting, but I particularly like Nathan's commentary. It's always interesting and he even updated the sidebar recently so most of the links actually work now. How pleasant.
It really is a good place to find out more about Central Asia from people who really are living here or even from here instead of the travel sites you usually find. Or the commentary from people who don't really understand this part of the world.
And who can forget the highly amusing Fashion Week in Almaty?
