In addition to the MSBuild documentation on MSDN and the MSBuild team blog, there is an MSBuild wiki on Channel9.  I had seen it before, but forgotten about it until I saw it mentioned in one of Chris Sells' old blog posts (My First MsBuild Task).

Here's the current table of contents for the wiki.
