I have been a happy subscriber to The Previous Magazine for a while now; I'd like to see a little more for profession software engineers, but otherwise always on the ball.
I second that - some more highly technical articles would be great. Heck, even an analysis of an IOCCC entry or something crazy like that. I know it may not appeal to most buyers, but it will appeal to some, and I think the magazine should have a little something for everyone.
