A quick note to tell you that the second edition of WordPress in Depth is starting to appear in better bookstores everywhere, and of course all the usual online sources. The book covers WordPress version 3.1, and has about 100 pages of new material compared to the first edition. Bud Smith and I are really proud of it.
I'll be highlighting some of the new stuff here in the coming days. Please let me know what you think, either in the comments below or through the contact form.
