Putting aside my feelings for the art (I'm not sure I like either visual version of the modrons), that was a great article. Really, really well written and great stories. It inspired me to use them in some way (if I ever get back to running a real campaign).
I also enjoyed the Kopru article - though I really don't like that style of art. I vastly prefer the more "realistic" art, which is 1 reason I probably won't be buying the compilation of ecology articles.
I haven't read much of the rest yet, as I just got the issue last night, but it appears to be another high quality production.
