I have been reading my groupmates' inspiring ideas about the possible ways blogs can be used in the classroom. How thoughtful of Nina to sum up all the important ideas re-the issue. I do think that blogs have a lot of potential for teaching linguistics as well as ELT (I am involved in both of these)

However, I firmly believe that blogging can be successfully used only if it is based on some problem-solving task. This will encourage my students obtain some data, conduct some research, synthesise and come up with the critical analysis of the data.

In ELT blogging can be used even more often. Our discussion on the Nicenet is a good example of this.
