Beware Dave Mark bearing new ideas. You’ve probably seen Dave’s name on the cover of the Apress Mac and iPhone books. Actually, his name is on the cover of this book. He’s the Mac and iPhone series editor, he knows how to get stuff done, and I wish I had half of Dave’s energy. And, if you’re a friend of Dave’s, he’ll put you to work. He’s put me to work over the years (in addition to my day job). “Hey, MarkD, I have this idea for an introductory Objective-C book. Why don’t you and Scott Knaster write it?” Sounds like fun, and it was. I still chuckle at some of jokes that we targeted to very narrow slices of nerdom. “Hey, MarkD, Jeff LaMarche and I have this idea for an iPhone SDK book, want to be technical reviewer for it?” Sounds like fun, and it was. Then they did another iPhone book, which I got to review. I discovered that this technical reviewing thing is pretty awesome.
