Are you still one of those people who don’t understand what RSS is? Wonder no more. The people at Commoncraft have made understanding very easy (I think).
I have tried my best to describe this to many people and I find that it works best to show it in action, which I do in many of my workshops and presentations. These guys have put together a great video though and it’s worth watching even if you are a pro since you may find it helpful in trying to describe RSS to the un-enlightened.
