I liked the Diamond's former bestseller 'Guns, Germs and Steel' a lot. It was a big doorstopper of a book, but its size was more than justified by the wealth of information it provided. Its approach and clarity seemed unique - at least in the field of popular science. 'Collapse' seems to be a clear attempt to discount the success of the previous book and was - at least to me - a rather disappointing effort. It's a pity, because the subject and even the angle Diamond took on it had undoubtedly a lot of potential.
