Amazon shoved this book under my nose in their recommendations, so I checked it out. On one hand, it's an "advice" book (red flag) and its page here is full of very suspicious-looking five-star reviews (another red flag). Otoh, the title sounds catchy, so I -- no, no, I didn't buy it -- I checked it out in our library (hehe).
I could barely finish it: it's hard to follow (because it's poorly written -- cogency is lacking: his thought jumps around a lot w/o easy-to-follow logical progression, at times descending into gibberish), and then it's just a lot of fluff -- his advice amounts to a lot of obvious things that would occur to anyone who'd invest a quarter hour into considering one's options (with traditional skippages in narrative over moments that look magical when not detailed, making you wonder who populates the skid row if everything is so doable).
It is also very cliched: every paragraph contains "value-laden", "remarkability", or "passion-based" this and that; horrible English and very bad style that is reminiscent of this late-night TV guy in black suit and with huge teeth who was big about fifteen-twenty years ago and whose name I forget. Usage errors. I mean, a lot of this book reads like a first draft by a not particularly literary man. Of course, the author has a website, and is some sort of self-proclaimed "career expert".
But in general, the most of this book is very superficial advice on how to use "social media" in order to inflate yourself into some sort of "expert" or "maven" (I'm sure you noticed that 99% of "social-media" content is horse manure energetically churned by self-proclaimed experts out to shove something down your throat that you don't need -- and advice on how to join the ranks of these hacks is not what I was looking for).
A lack of a standard bibliography section and an index do not improve matters either (every non-fiction, informational book should have those). Otoh, the books he quotes tend to be fluff as well (Godin, Rath, Gladwell and similar self-serving beschmutzers of the noosphere), so perhaps not much is lost. It's probably a cabal: they tend to promote one another's books; probably an unstated "scratch-my-back" obligation among the members of the crowd.
Bottom line: As time-wasting twaddle this book gets one star from me -- there's no reason for it to exist. Not recommended.
Added later: I find myself going back to this book for the sakes of the large number of website links in it. Since I am obviously extracting _some_ value out of this book, I'm bumping up the rating to two and a half stars. If I have to borrow it again from the library, maybe I'll simply buy a copy if I can find one cheap. Bottomline: not a good book, but as a catalogue of links it may be useful -- to some, perhaps, maybe.
