"Wiki in Plain English"

I had heard of wiki's before but I really had no idea what a wiki was until after this video. This video broke it down and made it easy to understand. I don't think there is anything bad I could say about it. Not only did it explain what it is and how it is useful, but also how to use it. I wish I could watch these videos for everything I learn. This would be very useful in the classroom because it explains things not only verbally but visually, which is beneficial for a variety of learners. The "In Plain English" series is great.
