My colleague, Jim Earley, has started a blog at: http://jims-thoughtspot.blogspot.com/index.html.
Jim and I will be co-presenting on a "Document Standards Interoperability Framework for DITA, DocBook, ODF and more" at DITA 2007 West.
Jim is an outstanding guy, and fellow DocBook, DITA and XSLT nerd to boot!
If you are going to be in the San Jose area next week, you should really consider dropping by! Hope to see you there!
