The new (supposedly expanded) edition of Don Tapscott’s Wikinomics: How Mass Collaboration Changes Everything comes out April 17th! I’m not sure how much expansion they could do from the first edition, unless they just update the case studies. There has been so much in the past 18 months will social and group-think sites, that it has become obvious, to even the most stuck-in-the-mud businesses, that collaboration is the future.

Let me know if you run across any advance reviews out there. I’d like to read them and see if the new edition is worth buying.
