Elluminate and I-chat and Skype...oh my!

For the first time in this class, I was a little overwhelmed today. I have seen and heard of Skype, so I was a bit familiar with it, even though I have never used it. Elluminate was a different story, as was i-chat. There was so much there that I was having a little trouble following along. I can see some value in these programs - I like the idea of having "experts" talk to classes and I think it would be great for math classes to hear from people like engineers or economists who use math in the "real world". Skype seems like a great way to do this.
