I found a number of the essays completely engrossing... the two on the US, Japan, Australia, and Sweden. The UK was interesting, but I didn't have a lot of interest in France, Germany, and Spain. I think the problem was that some of the writing wasn't as strong. Spain is actually a fascinating case study on bridging vs. bonding social capital, but I had difficulty getting through the article.
Overall, you have to really be into social capital to like this book, but I would recommend it as a follow up to Bowling Alone and Better Together.
