Here is an interesting blog called Begging to Differ. It's a multi-moderated blog with two authors who are liberal and two who are conservative. They discuss politics, culture, and law. Though I've not spent a lot of time there, it looks like an interesting read. One of the articles was about an English professor at Georgia Tech who is requiring his students to participate in a class blog, with each person doing writing assignments on an individual blog (student links are listed on the main blog). This looks to have real potential as a teaching tool- I think it's a terrific idea! I'll definately be taking a closer look at these two blogs, and thought you guys might want to also.
