So what is a feed?
RSS stands for (depending on who you ask)
•Really Simple Syndication
•Rich Site Summary
Basically, websites collect their stories and ‘send’ them out to various readers
A reader is a software that allows a user to view (and sometimes hear or see) headlines, summaries, complete stories, etc.
Examples of ‘readers’ include Firefox (live bookmarks), bloglines, newsgator, pluck, etc.
Think of RSS as the newspaper or the morning news you listen to. Each day is fresh, and the content is available to you. All you have to do is open the gateway (a newspaper, the tv, computer, radio, etc.)
