Who is Kristian? Why should I care about his blog?

Good questions. Kristian Kielhofner is the creator of AstLinux (and main maintainer of this site). If you are interested in AstLinux you will probably be interested in a lot of the same things. Kristian writes a lot about AstLinux, Asterisk, VoIP, networking, telephony, the industry, etc in his blog. You might find it to be a good read.
