I'm a developer on the Confluence team, and I started at Atlassian in January 2006.
Unlike some of the other Confluence developers (Charles and Jens for example), I'm more of a Windows/Linux guy than a Mac guy. Although I am thinking of getting a Macbook this year.
I'm very interested in web development, specifically accessible and semantic site design. Wikis are actually one of the most interesting areas of web development, I believe, because they're a totally new form of content. Blogs came from the idea of personal journals, some websites are like marketing brochures, but I think there's nothing comparable to a wiki in the physical world. On a wiki you can create an array of linked and searchable content, then anyone can improve on the words you've written, collaborating on whatever you want.
You can also read my personal blog, but what I say there has no relation to the opinions of Atlassian or its staff.
