Rich Site Summary
<networking> (RSS) A family of document types (generally based on

RSS documents (generally called "RSS feeds") are readable with RSS readers (generally called "aggregators") like
BottomFeeder, although, in 2003, it is anticipated that aggregator functions will be incorporated into web browsers and/or NNTP newsreaders.
