There is Yet Another Architecture Journal (YAAJ) that has been posting some interesting reads in the last year or so. It has something from pretty much every talking-head, blow-hard, or egomaniacal pundit on the architecture scene today. There are actually a few decent architects and writers represented too. For example the article on Service-Oriented, Distributed, High-Performance Computing actually serves as an excellent primer. While there is nothing new or even translationally creative, it is an excellent starting point which sets the terminology and foundational concept bar at an adequate level. There are several other interesting pieces if you surf around a little.
Oh, and Harry, and I'm still working on getting the reading list published.
