The practice of hosting a Barcamp is well known and documented. For participants, the rules are simple. When it starts, it starts. When it ends, it ends. Whoever is participates is the right group of people. And everyone is responsible for following the law of two feet.
You may have noticed that when it comes to Events, . Soon there will be 3,000 presentations from Barcamps all around the world. And with support for video, the sharing will only get richer. In every camp I've hosted I tacked on another request -- to document and share the session you are in for the people that can't be there.
Now SlideShare has created the Barcamp Channel, bringing together the presentations, documents and videos from Barcamps around the world in one place. Its still rough, but will be great to see what emerges.
