What is RSS:
(http://xml.com/pub/a/2002/12/18/dive-into-xml.html)
"RSS is a format for syndicating news and the content of news-like
sites, including major news sites like Wired, news-oriented community
sites like Slashdot, and personal weblogs. But it's not just for news.
Pretty much anything that can be broken down into discrete items can be
syndicated via RSS: the "recent changes" page of a wiki, a changelog of
CVS checkins, even the revision history of a book. Once information
about each item is in RSS format, an RSS-aware program can check the
feed for changes and react to the changes in an appropriate way.
"RSS-aware programs, called news aggregators, are popular in the
weblogging community. Many weblogs make content available in RSS. A
news aggregator can help you keep up with all your favorite weblogs by
checking their RSS feeds and displaying new items from each of them."
Well, that should be it.
