Via Anne Laurent, a very cool video explaining the power of wiki at its most basic level. Presenting...Wikis In Plain English (complete with cool theme music!):

Too often, we hear about the limitless possibility of wikis to do anything. But if a leader wants to know what implementing a wiki can do for their organization, the word "anything" isn't a helpful answer. What is a helpful answer is the basic value proposition put forth by this video: Wikis coordinate and organize a group's input.

To demonstrate this idea, the video uses the example of four friends planning a camping trip. But what if instead of four friends, you had 35,000 colleagues scattered across the 16 agencies that make up the United States Intelligence Community? Well, then you'd have a little something we like to call Intellipedia. It's just a bigger application of the same basic idea.

At the Academy, we believe that the business challenge, not the technology, should drive the implementation of collaborative tools. This video serves as a reminder of the kind of business challenge, at the most basic level, that wikis can solve.

The video comes from a Seattle-based company called Common Craft. They have a few more videos, all of which are worth watching.
