Facebook as an Educational Tool? - Podcast

I really enjoyed this podcast. I think it was very interesting how they did a question/answer interview type podcast. This made it a lot more interesting because I was able to see both views. This podcast almost sounded like a salesman discussing Facebook to a customer trying to persuade them to make an account which definitely kept my attention. I know that when I do my podcast I will want to do something similar to this, but I think it would be better if there were more people included to make it more interesting. I would like for my podcast to keep the listener interested as well as informed about the topic.
