Two quick ExtraBITS this week: Michael Cohen discusses his new book, “Take Control of Pages,” with MacVoices host Chuck Joiner, and the new online publication Design Explosions compares Google’s and Apple’s approaches to mapping in iOS.
 -- For Take Control authors, it’s inevitable, but always fun, to finish a book and then get to spend an hour discussing it with Chuck Joiner of MacVoices. Michael Cohen’s most recent chat with him was no exception, as they discussed the book, how it came to be, and why Apple made Pages into the three-platform app that it is today.
 -- A new online publication, Design Explosions — the brainchild of UX Launchpad — kicks off a series of “design lessons” with an in-depth look at how current Google and Apple iOS mapping interfaces work and why. Design Explosions assumes that product building teams are smart and talented, and that there are well-considered reasons that underlie why the products look and work as they do. Its in-depth analysis of Apple Maps and Google Maps on iOS makes for a fascinating and informative read, and provides a welcome respite from the usual “We Look at Two Interfaces and Tell You Who Won” type of critique.
