Over at the 6A Pro network, Brad Choate has written an overview on MT's new dynamic publishing feature. This is just what I've been looking for, something to tell me just how the dynamic publishing is implemented and it's definitely more informative than what's in the MT documentation. I think it's something that will help a lot of people learn how it works and how to use it effectively. It's not really a tutorial on how to do the dynamic stuff, although there are some examples provided. It does provide a lot of good information showing what's behind the scenes though.
