A lesson for your classes this week — the power of the Internet during a crisis or catastrophe. The latest example of how the Web joins in to get vital information out is the Gustav Information Center, a wiki created on Ning by Andy Carvin. This wiki, which I joined (see my widget at the bottom of my sidebar), is providing news updates, weather maps, photos, forums and videos. Teams of people are working on getting the word out to families, pet owners and others on a minute-by-minute basis.
It would be a great class lesson to examine the online efforts of individuals and groups to get the message out instantaneously during events like hurricanes, tornados, natural disasters or large-scale violence.
