RSS means Really Simple Syndication.
SS feed is an XML-based file. To give anyone access to the information contained in the feed, the feed must be placed on a Web-server. An RSS feed can contain various information beginning with your corporate news and ending with the daily menu of your neighbor’s dog.
How to Create RSS.
Nowadays, you don’t have to write RSS-code manually as there are many programs that can create RSS feeds in the WYSIWYG mode. To make use of such software, you don’t have to know XML or the RSS specification.
Feed Editor: create, edit, and publish RSS
Feed Mix: mix RSS feeds, make RSS
Finally, if you want your RSS feed to become truly popular, then, besides a stream of new users, it needs a constant audience of readers that will take part in the development of the feed and leave comments.
