Having just recently seen lots of interest in Bricolage, I must admit I'm jealous of all the developer interest in Mason. I think Mason has many cool features, but it's very hard core Perl. So I was blown away when I found out about these guys, who are almost done developing a CMS using AxKit. Awesome!
Before I had to find permanent work, I was still working on AxKit.com's CMS product, because I think it's a really killer use of XML. Nice to see people other than me see it that way.
