I'm pleased to announce that I've posted an XHTML version of Pro Web 2.0 Mashups: Remixing Data and Web Services. This should make it much easier for folks to use my book. It also opens up some good opportunities for me to update the book, which I plan to do as I teach my Mixing and Remixing Information course this semester.
A warning: the XHTML translation has some technical flaws that I'm working to fix. However, I figured that it was better to put a working version up and then fix it along the way.
Enjoy and let me know what you think!
