I'm tempted to buy it just to see what it is. It's on B&N as well. It's weird especially since they mention some local Hackerspaces such as NYC Resistor (based out of, duh, NYC) and Pumping Station One which is based out of the Chicago area and, if memory serves correct, is only over a year old. The book might prove interesting or it might just be a printed version of those websites that have a shitload of keywords on them so that if you google for anything (such as a random phone number) the search result will bring you to an ad filled page.
