In looking through the materials listed in the 2nd "tool" of my training, I was interested in a few things. Although I found the commenting tips a bit obvious, I agreed with the point that this etiquette certainly needs to be taught directly to our students. Commenting on a blog is something I have done before and I have had my own blog and received comments as well.
Also I had never heard of social bookmarking and would like to learn more about the applications of this in the classroom. I will definitely pursue more information about www.diigo.com.
A blog I plan to use in the future is: http://www.thertiblog.com/ This blog has a lot of information about RTI and its implications in our schools.
