I'm a weblogger. Standard-Weblog-tools like MovableType, pMachine, SunLog, ... are not XML-based. So i decided to develop my own weblog-tool based on cocoon.
We also use cocoon in our company, but we have a bigger Web-CMS called "iProject" (PDF, german).
Until my Cocoon-based-Weblog is ready, I use a 20six-Weblog: 26.schlaudenker.de (german).
Another project (T-Dings.de) is already made with cocoon.
My UUID is 52452a02-f8ab-4bef-8836-5384ee9149a7.
