What is it used for?
There are two ways in which an RSS feed can be used:
- for one's own personal information: to subscribe to and check all the latest information of websites from one single place, without having to visit all the sites. Essential for searches and to follow the activity of open cooperative devices and also to ensure an “ex-post” moderation…
- for a webmaster to syndicate content, which means publishing information coming from other websites automatically on a website. This is essential to grow the networks, and to avoid publishing the same information twice, to make one's site dynamic without becoming exhausted ;-)
