Socialtext has come out with a brilliant case study, summarized on their site blog, in the articleVisualizing Socialtext Collaboration. It’s a wonderful example of using SNA to see the patterns of interaction in an organization.

Even more interesting is the related case study, Ziff Davis Media Accelerates Project Cycles and Reduces Group Emails from 100 per Day to Zero. The case demonstrates that the use of the wiki-based Socialtext[TM] platform saves Ziff Davis an estimated $1M/year just by reducing the emails.
