In addition...
In modern browsers (*cough* Firefox) the RSS feed can be placed in a bookmark folder. When you look @ the "bookmark", you can see the current news on the site as a list of links. This is extremely useful if you visit at set of sites on a regular basis.
I have a picture of an RSS feed (example) available @

As you can see in that picture, the news from the website (slashdot.org) shows up as a series of links in my browser. Very useful indeed

.
Even cooler, for websites that embed RSS in their HTML code (as the Link Rel statement above does) Firefox "identifies" this line of code and gives you an RSS icon in the lower right hand corner of the browser. So basically, you can subscribe to an RSS feed in one click.
Firefox also allows you to utilize multiple style sheets (a word us web developers recognize) on a single site. So changing the theme of a site is as easy as clicking a button (lets see IE do this one).
If you download firefox, check out Bluesnews.com -- they use multiple style sheets (a small icon in the lower right hand corner allows you to switch the site theme).
