Via pafa.net, I found this very nice piece that touches on screencasting vs. slidecasting. The best thing is that it provides a nice, quick look at the tools involved to create both. They’ve even included some of my favorites such as Wink, Camtasia and Audacity. If you’re just getting started with either type of “casting” this is definitely worth a look.
