How to RSS?

RSS-ify

OK, I have to go back and read this and try to figure it out tomorrow- What does RSS do for me that making links (Or going through a list of Safari bookmarks does not? Why can't I just keep adding links to the sidebar and then go through and click on them? I think RSS is supposed to mean that I will see the headlines directly and that will save me from having to go to the site and surf around...

Other things I've come across that I need to learn more about:

Flickr
del.icio.us
blogrolling
furl
podcasting

And why won't the little add web link icon above add a url?
