RSS stands for "Really Simple Syndication" or "Rich Site Summary".
Feeds are a way for websites to distribute content well beyond just visitors using browsers. Feeds permit
subscriptions to regular updates, delivered automatically via a web
portal, news reader, etc. Feeds also make it possible for site
content to be read by mobile devices. Many of the news readers will
allow you to set the interval that the software will look for a feed
update others simply update daily. The information in the feed will
be updated when the feed contains new content.
