I had the opportunity to read through this book over the last week, and I'm just floored by how much good information it's got in it. This book is years of Patrick's experiences running successful forums (22 forums now, I believe!) and all the tips, tricks and wisdom he's picked up during those years. I ran a moderately successful forum years ago, and would have saved myself months of headache and heartache had I the information in this book at my fingertips back then.
The book is definitely opinionated - these are Patrick's recommendations based on his experiences, and it shows. His voice is natural, and the wording is down to earth. This isn't some theoretical treatise, but a 'from the trenches' view of what works, what doesn't, and why.
The book includes many sample forms which have example language to use for welcoming members to your forum, working with moderators, dealing with abusive or disruptive visitors, and much more. They're all available on the book's website too, so you don't need to retype it all in, but can quickly customize them to fit your own needs .
The one thing lacking in this book is that it doesn't go in to much detail about the major forum packages out there, so the reader who is just starting out will have to do some more research as to what packages have which features discussed in the book. Having said that, this keeps the focus of the book more on the human/people side of internet forums, and doesn't devolve in to a technical manual. I would have preferred a small feature comparison of the big forum systems out there, but I'm more of a technically-inclined person to begin with. If you're not technically inclined, you likely won't even notice the information not there.
Bottom line: if you're thinking of starting a web-based community, or have one and aren't sure how to manage it, this book is a must-have. It will save you weeks, if not months, of getting up to speed and being as effective as possible with your forums.
