Nice commentary on NPR about Wikis from David Weinberger. Humorous overview of what wikis are for the masses. If you already know what a wiki is you’ll enjoy the intro, “Here’s what sounds like a really bad idea. Let’s post a web page… when we get it just the way we want and when it’s perfect we’ll let any stranger who comes along change it.”. He even found time in the three minute spot to explain what Social Software is.
