Unmediated links to a couple of real-world events which are using social software in really innovative ways.
Northern Voice in Vancouver, B.C. , last weekend, used tags as a way to create an extended event. The site is a blog. They provided ways you could subscribe to PubSub, Technorati and other feed services. They aggregated headlines from what people had to say about the event from around the web. Their wiki kicks butt.
Unmediated also points toTED in Monterey which are doing similar things, and calls these things “X-Events” which I like; we certainly need some kind of name for events and conferences which use existing tools like Flickr, Delicious and Technorati to plug themselves into the virtual world. I particularly liked the way people were taking collaborative notes at Northern Voice using SubEthaEdit.
