The folks over at MSDN asked me to author a series of articles based around the theme of the "Pragmatic Architecture" talk I've given in a couple of locales recently, and the first article ("Layering") has gone up, along with the introduction to the series. Feedback is, of course, welcome, through either blog comments or through more traditional channels.
By the way, here's an interesting challenge for those of you who think you're up for it--who are the two members of "the group" spotted by the author during the intro? (Yes, they are, in fact, real people. None of this "Any similarities to persons real or historical is strictly accidental" bull-pucky for me.)
