I have just finished reading Groundswell by Josh Bernoff of Forrester Research. The book has been around for awhile but its concepts are worth understanding. Its a great book about how Social Technologies have changed the way companies relate to their customers. Not only that but how companies can benefit from Social Technologies within their own organisation. Its a good read, get hold of a copy. The book is rich with Internet law, marketing tips, research and good practice. It gave me some ideas on how Groundswell could be used to provide a product owner with some powerful tooling.
