I was familiar with Skype and had used it numerous times while I was travelling overseas to talk to family and friends. I have used it professionally in the past for job interviews and found it a successful communication tool.
The Skype session I conducted with my group was the first time I had Skyped with three people. We were unable to get the video to work because it was a feature that required us to pay. I think it would have slowed the speed of the connection if we used video anyway. It was an enjoyable experience, but was hard to read social cues. I often found that I didn't know when another person was going to speak and began to speak over someone else on a number of occasions.
One of the features that makes Skype enjoyable is the function to 'chat' at the bottom of the screen. It allowed us to share links to web pages we were looking at and store information, like email addresses, for the future.
Overall, Skype was fun to play with and I will definitely use it in the future!
