By the time a printed publication reached my hands, a large part of it's contents would likely be out of date. For that reason, I canceled my local newspaper and numerous magazine subscriptions this past year. Something in the form of a PDF that I could optionally print may be useful.

The more WordPress websites the merrier in my opinion although I do wish some of the well known developers would produce more in depth content that has longer shelf life. For example, Small Potato's "So you want to create WordPress themes huh?" is still a very valuable resource.

BTW, http://net.tutsplus.com/category/tutorials/wordpress/ does a great job of getting quality WordPress tutorials in one place.
