YouTube

Here's a link to a useful video on YouTube that explains blogs.
It was produced by Lee Lefever for the CommonCraft Show. He makes short professional trainingvideos on technology topics, such as blogs, wikis, podcasting, and twitter. The videos are explained in plain English, for beginners. They are good for personal use, but could also be used in technology training sessions in a workplace.

I use YouTube on a regular basis. It is entertaining in that you can watch old clips from TV shows, and it is informative as you can watch news reel from current events. It is open to anyone to publish anything (within reason), and is a great equalizer. I'll continue to use YouTube in the future.
