I have no previous knowledge or experience of crowdsourcing - beyond a vague idea about what it is. This both expanded my knowledge and opened my eyes about the possibilities that it represents. I had never thought that things like Wikipedia is a "crowdsourced" project, but of course it is and it alone shows what is possible.
As usual the For Dummies style is both entertaining and informative. I guess it is a style that does not appeal to everyone, but I love it. Anything that both informs and makes you smile at the same time is not bad thing.
For anyone using the internet commercially I'd suggest that this sort of book is a must-have, especially for small start-ups looking for ways to generate funding. Crowdsourcing is neither easy nor foolproof, but you need to know about it and it's hard to think of a better way of investing fifteen quid or so than buying this book. John Birch
