This is one of those books that doesn't so much tell you things you don't know, but rather confirms things that you do know. If, like me, you've always thought that people 'working' in marketing, PR and the media, were taking the piss, you'll really enjoy this book.
Most of the stories are very funny, but some of them did make me quite angry. The author certainly knows his subject, and does a good job of keeping you interested and he throws in some great stuff about growing up in the eighties - Led Zeppelin, Bullseye and careers lessons for example. For me, working in a large IT department, the chapter on the millennium bug was the best.
If I did have a criticism it would be that at 192 pages it's a bit on the short side, but that should detract from the fact that this is a very funny and insiteful read.
