I listened to two principals who have a series of podcasts. Scott Elias and Melinda Miller have never met but they have developed multiple podcasts together. Milinda is an elementary principal and Scott is an assistant principal. In the podcast that I listened to, they reviewed twenty two different technology tools that they use and like. They mentioned Twitter, Skype, Video and Audio Chat and their favorite is the IPhone.
The description of the multiple uses of Skype was new to me.
