RSS is a great technical tool for subscribing to internet based blogs, and can be used by classroom teachers to exchange the latest and most informative techniques. The thing that I like most about this tool is the possibilities it offers. I was able to easily figure out how to connect with other blogs and users.
In my personal life I can see this being used for local and national news updates allowing me to focus on items that I would find interesting and useful.
Many authors have blogs that they update frequently which can promote interest in the classsroom.
