If your not sure about social software for the business or how you can benefit from using social software at work, I urge you to read the Lotus Connections Reviewers Guide. The guide, co-authored by yours truly introduces the first social software ready for business. It outlines how IBM have been following social software over the last couple of years and been using the 5 services of Lotus Connections internally. Also learn how Lotus Connections can be extended into Lotus Notes, Lotus Sametime, and WebSphere Portal.
