Read RSS feeds
You can publish an RSS feed for your own site, but you will probably also want to read the RSS feeds of other sites. RSS is great because it lets you separate desired content (what you want, what interests you, what is relevant to you) from undesired content.
Reading RSS manually
You can read RSS manually in your browser by putting the URL of an RSS feed in the address bar (Try it with our RSS feed) or by clicking the RSS icon that appears on the right side of the address bar for sites that offer an RSS feed.
RSS feed readers
Using a feed reader instead of reading RSS manually gives you much more options.
There are many feed readers available. Some web based (you use them through a web browser), and some as separate programs. RSS feed readers have many features including searching through feeds, sharing feeds with others, assigning keywords to feed items, and much more.
Web based RSS readers
Google Reader, BlogLines, WizRSS (add-on for Firefox)
RSS readers software
FeedDemon, FeedReader, SharpReader, RSSreader, blogbot (add-on for Outlook & Internet Explorer)
Subscribe to feeds
To subscribe to an RSS feed you need the URL to that feed. To get this URL find the 
or 
button on the site whose RSS you want to subscribe to, click on it, and copy the URL that comes up in your address bar. Open your RSS feed reader, find the option to subscribe to a feed, and paste the URL in there.
Filter feeds
Many RSS feed readers have the option to filter incoming feed entries by certain keywords. This is very useful if you're looking for particular information in an RSS feed. For example, if you are subscribed to the RSS of a jobs site and you want to get only the feed entries that list freelance jobs you can filter this RSS feed for the keyword 'freelance'
