just got mine this morning — I thought I saw in the editor's note that you had no prior design experience. I don't believe you! =) Looks really, really great.
My only criticism is the giant blocks of text — breaking them up with a pullout quote/picture/chart would do wonders. (I worked in newspaper layout before getting involved in programming)
If you're looking for a design book, my newspaper swore by Tim Harrower's "Newspaper Designer's Handbook".
But again, excellent job! I'm excited for future issues, and, like @almost, you can also definitely count me as a subscriber.
