Here’s one of the real successes of the “Open Space” conference model: I’m interested in wikis. I have some personal/business projects that I would like to collaborate on and wikis seem like they might be a good application. So I threw it out there as a topic idea, got my space, and Viola! An instant session on wikis.
Several people came together to share what they knew about wikis, to talk about how they want to use wikis, and Doug Sorocco gave a great demonstration–ad hoc–installing a wiki and editing some pages on the fly. This was exactly the kind of session that makes a conference like this great.
