This morning I helped a student conduct a college interview via Skype. It was supposed to be through Yahoo Messenger, but we couldn't get the video to work (probably firewall related on our end) so I asked the college admissions officer if she would consider downloading and installing Skype. She hadn't heard of Skype but said, "Sure, let's try it." Four minutes later she called me on Skype and they conducted the interview with full audio and video.
It saved the student a plane trip and waiting longer to find out about college admission. I got to see/hear her get accepted to her first choice school.
