Now that I'm mentioned on the wiki, maybe this is a good time to create my own little wiki-page. I worked as a java programmer, and stumbled upon cocoon shortly after the year 2000. I used to work at Hippo Webworks, where I introduced cocoon and helped to build a CMS around it. I am now self-employed as a cocoon/xml/open source specialist and I am currently working for Be Value to help them use cocoon in their projects, especially at a major Dutch publishing company.
My (fledgling of a) site is at http://www.hivemind.nl, more to come.
