Description:

News aggregators read news, weblog or other feeds over the web and
aggregate them so the news items are readable from a single place,
regardless of their source. The data format aggregators utilize to do
their job is called RSS, standing either for Really Simple Syndication
or RDF Site Summary, depending on who you ask. At the moment, there
are two different, incompatible specifications, with different
objectives: RSS 0.9x/RSS 2.0 and RSS 1.0. Straw supports both of them.

To find feeds to subscribe to, look for a white on orange XML icon,
XML icon, on web sites. You could also use a centralized syndication
service, such as Syndic8.com.
