Swarthmore College's WNR radio station is using Skype to interview people living in Iraq and then podcasting the resulting program. This use of technology is so elegant and powerful that many more programs like it are certainly possible. If nothing else, WNR's content is certainly worth considering for social studies classes. I especially liked the interview about where Iraqi people go on vacation and why.
They find the people they want to interview by using Skype's ability to list users by country and then by language. So WNR simply searched for English speaking users living in Iraq. Just imagine how many ways this capability could be used!
