More of two cents note on the hold RSS has taken and it's increasing popularity.
I equate an RSS feed to the news "ticker" that we see every day if we flip through the TV and pass by ESPN, CNN, MSNBC, etc. and of course just about everyone in the world has seen the "tickers" that run across buildings in NYC.
Just note that although you can't judge a book by it's cover you decide to pick it up or leave it depending on the title. That's why headlines are so important in newspapers and as we shall see to RSS feeds.
