I enjoyed it overall, even though the edition I own is set with a too small point-size and too much text in one page, offering a bad reading experience. (Think of it as a 220 x 1.5 = 330 page book.) Add to this the fact that the content sometimes gets too technical and dry, and it verges on a boring textbook.
I found it interesting that in a 7-page section titled "Models of Cultural Evolution" where he elaborates on many theories/models by various people, he only mentions Dawkins and memetics once, in parantheses, without any explanation.
