I started reading the book with great interest as part of my field of study, however, heavily loaded with examples and with concepts basically thrown in, the whole text became a salad bowl of unrelated, unmatching ingredients that in the end leaves a taste of cellulose. The book is supposed to be about sharing practices in cities. It talks about all sorts of sharing practices not necessarily pertaining to the cities, delves upon different literatures on culture, history, economics and more, giving a feeling that the authors want to show off how much they know, but seems like they don't know how to focus and edit a text in a way that is going to appeal to academic and non-academic audiences. I personally had a hard time filtering the unnecessary information, examples, histories etc. to cut to the chase and get what the book itself contributes. It's all over the place, often repetitious (in several instances "we talked about this in Chapter X and we'll talk about this chapter Y) , and if it wasn't for the few charts and summaries in the second half of the book, it would certainly leave the reader with more ambiguity than clarity. (Ambiguity in text may be desirable in certain instances, but this is not one of them.)
