Poplorica is quite an interesting read--the authors have chosen 20 innovative ideas, things or trends and written essays on how this particular thing has drastically changed the face of America, at least in its own little slice of life. All chapters are interesting, some more interesting than others--but that's probably going to depend on the reader's interest anyway. The book delves into assumptions many of us take for granted (and the younger you are, the more of these assumptions you probably do take for granted). For instance, what was music life like before the electric guitar. If it weren't for Les Paul and other innovative musicians, we wouldn't have those fabulous guitar solos we so enjoy now. Why does every suburban house have a lawn? Did you ever stop to think about all of the changes the disposable diaper made possible? This is an entertaining and thought-provoking book, if only because it makes you think a bit about various aspects of American culture and how they got they way they are.
