The Bloggers Guide to Biztalk
If you're into BizTalk 2004, you've gotta have a look at this cool help file (.chm) that was put together by a bunch of BizTalk Bloggers (and according to the doc it'll be updated on a monthly basis). Very cool idea as you'll see the content reads very much like a blog in that it doesn't have to be super polished and as a result ends up being very down to earth and easy to read and absorb. So you end up with a gathering of some fantastic blog entries in the convenience of a help file.
Here's the folks behind the creation of it, and their blogs (this is also contained in the guide)
