Weblogs and news sites are the most common use of RSS feeds. When new content is added to a blog or website, that contect is automatically updated to every subscriber of that RSS feed.

I got a comment by Elizabeth Hanson-Smith ( a Webhead) about how she uses RSS:
Long ago found I just didn't get around to visiting a place likeBloglines to read RSS feeds, so instead I use <http://Feedblitz. com>which emails me any time there is new material on a blog, Web page,wiki, etc. So the feed comes to me, rather than my having to gosomewhere to find it.I have a FeedBlitz "button" on my Firefox browser for quick and easylinking, and FeedBlitz tells you immediately if you have anRSS-addressable link. The only inconvenience is that sometimes I haveto "View Page Source" to find the RSS address, and copy and paste itinto FeedBliz.Cheers----Elizabeth
