I've used Skype before on a personal level to communicate with family and friends that I don't get to visit often. I'm thinking I would like to use it in my classroom to have my students communicate with another 2nd grade class in/or outside the district. Not sure yet.
I just created a Wallwisher account; so, I'll see how this works out. I'm thinking we can use it ask questions about homework or to share current events or to share interesting facts about classwork we may be doing.
