What I know..... :-/

I really don't know that much about Podcasting. I know how to see videos on youtube, download music, and that's all. I would love to learn as much I could since we are in time where technology is big component of life. I think in a classroom environment it will reach out to other student who may have not been interested before. I am not quite sure although maybe teachers would use it too much and the children would get bored of it?
