Video: RSS in Plain English

I was thinking about some post that will explain RSS concept to people which don't know it and don't use it for some time (and mainly to increase my rss subscribers count ;-)).
I just found this video and i think there is everything you will need to grasp RSS idea and it is said in better words i will be ever able to think off.
So enjoy, please, put attention to last sentences. RSS reader is highly addictive :-D.
