Anyway, back to the point of this posting. CC, yet again, does an amazing job outlining the bennies of using RSS. In short, if you read multiple blogs and find it time consuming having to pull up each and every site that you enjoy reading then RSS can help simplfy your life. I, for example, currently subscribe to some 50'ish blogs which I've broken down in to 4 categories (Green, Art/Design, Tech, Peeps). By using Google Reader I can now monitor all of my blogs/news feed updates in one place from any computer.
