From a publisher perspective, a web feed is a data format used to provide users with frequently updated content. It allows the publisher to 'syndicate' its content to many sources at once.
From a user perspective, feeds offer a way for web content to be selectively tracked, subscribed to, and perhaps customized into a personal service. Webmasters can also re-publish such feeds on their own websites.
These feeds are frequently called RSS feeds, where RSS stands for Really Simple Syndication.
In web terms, content that is syndicated (e.g. as a news feed) can be incorporated and displayed on other web sites or accessed directly with newsreader software such as iGoogle or bloglines. Syndicated content normally comprises headlines with brief descriptions of content that link to the original story or news item. Feeds can be combined using online aggregators that help filter or select content to read or re-publish.
