Simply put, Skype can be used to communicate with anyone, anywhere, anytime, via text, voice, or video. If the other person has Skype, it is free. Otherwise, there is a small fee to call land-lines and cellphones.
I use it ALL the time with my Personal Learning Network (PLN) to collaborate, communicate, and share. I also use it at Wissahickon to communicate with teachers who have questions and need a quick answer. I have even shared it with my family and my father in Florida uses it (on his MacBook!) to show me the sunset in the Keys. Very nice indeed – for free!
