Groundswell is that rare combination in a business book: Simple concepts and detailed explanations of what to do and how to evaluate the results. I especially liked the case histories that measured the economics of customer engagement.
The authors draw on their experiences at Forrester Research to show how right and wrong you can go by listening to, speaking with, engaging, providing for, and cooperating with customers. They caution starting small and feeling your way. Otherwise, you may bite off more than you are able to absorb.
For smaller companies, you'll also find suggestions of lower-cost ways to use social technologies that you can afford. Naturally, the options are more diverse and expensive for larger companies. But if you are spending a lot of time on marketing research, advertising, and promotions, you will probably find social technologies a less expensive way to go. If you have major expenses for customer support, social technologies can eliminate a lot of those. In addition, social technologies can help you gain faster insight into defects. For the lean company, these approaches will also make a lot of sense.
I liked the book so much that I included several references to it in my weekly briefing to entrepreneurs who want to build major businesses.
If, on the other hand, you are doing a lot with private communities, help forums, executive blogs, and evaluating customer observations, you won't find this book to be advanced enough for you. It's more of a beginner's guide.
