Here is the periodic sampling from my del.icio.us favorites list. This time I chose the tag "Unconference."
Wikipedia's definition: "An unconference is a facilitated, participant-driven conference centered around a theme or purpose. The term "unconference" has been applied, or self-applied, to a wide range of gatherings that try to avoid one or more aspects of a conventional conference, such as high fees and sponsored presentations."
This is what I found I have:
The unconference - a new model for better professional communication: A white paper published in Lianza that is both a how-to guide and analysis of the value of and uses for unconferences in professional development.
Event organisation - Unconference: From Interactivecultures, a brief blog post on how to host an unconference.
