Feed Reader

Aggregators reduce the time and effort needed to regularly check the website for updating information, and create a unique information space or "personal newspaper." If you already subscribe to a feed, feed readers will be able to check for new content based on user-defined time interval and obtain new information. Loads the content is sometimes considered to be "pulled" by customers, as opposed to the "driven" as the sender's electronic mail or instant messages. Unsubscribe any easier by the aggregator user than the user information "pushed" the other.
Recommended feed readers are often installed as a default within a portal site (such as My Yahoo! And iGoogle), modern browsers, and electronic mail client program.

To take advantage of this technology we need the collector service. Collectors can be conceived as a personal mailbox. We can then apply to sites that want us to know the changes. However, unlike a newspaper or magazine subscriptions, subscribe to RSS unnecessary costs, for free. But, we usually only get one line or an introductory address from the contents of the following sites related to reading the full contents of the article.

Use
RSS is widely used by the weblog community to spread a summary of recent writings in journals, sometimes also include the complete articles and even pictures and sound.

As written above, there are several versions of RSS, and even some groups to make the new Atom format that has also been adopted by many sites. But users do not need to be confused RSS, syndicated collector program makers are usually able to recognize both that format, even still allow the reader to the old format.
