If you are a regular reader of this blog over the past few years, you have seen news and insights about social business and the growing sharing economy. In fact, the reason I have been blogging a little less in the past month is that I am working on an ebook on the topic. (Watch for it in the next month or two!) Luckily, Altimeter Group just made the job of researching and writing my ebook a little easier. The firm, which has embraced a sharing model itself in how it collects and distributes research, has justpublished a terrific report on the sharing economy.
