Podcasting

Anyone did it? I mean made a feed that I can subscribe to. I am getting ready to do it and I want to do it right but it still be easy. I know there are sometimes ways to do things and it be kind of rinke-dink lol. I want a nice feed done, for any podcatcher and itunes too. I have some stuff I have read that have made it pretty clear but if anyone one has any experience please pass it on help me avoid the pitfalls of being a first timer!!! Thanks
