I have been talking recently at conferences (OSCON and FooCamp) about the Art of Community as part of a project that Danese Cooper and I are doing for O'Reilly Media. We are in the process of writing a book on the Art of Community, which will start as a wiki with plans to write an initial first draft of the chapters, post them to the wiki, and allow the community to be our editors / collaborators on the project. We also plan to record a bunch of podcasts to include on the wiki and use as vignettes in the text of the book. We are still in the process of writing the chapter drafts, so the wiki is not yet public; however, we are looking for input and ideas.
If you have something interesting to say about community and would like to talk to us, please contact me: dawn at dawnfoster dot com.
