What are feeds? I see "RSS", "XML", and "Atom" out there, but I don't know how I might use these links when I find them.
Feeds are a way for websites large and small to distribute their content well beyond just visitors using browsers. Feeds permit subscription to regular updates, delivered automatically via a web portal, news reader, or in some cases good old email. Feeds also make it possible for site content to be packaged into "widgets," "gadgets," mobile devices, and other bite-sized technologies that make it possible to display blogs, podcasts, and major news/sports/weather/whatever headlines just about anywhere.
What Does This Mean?
You may recognize the universal feed icon or these "chicklets" from your favorite websites, blogs, and podcasts. These icons represent content in any format - text, audio or video - to which you can subscribe and read/watch/listen using a feed reader.
How do I read feeds?
If you want to browse and subscribe to feeds, you have many choices. Today, there are more than 2,000 different feed reading applications, also known as "news aggregators" (for text, mostly) or "podcatchers" (for podcasts). There are even readers that work exclusively on mobile devices.
Some require a small purchase price but are tops for ease-of-use and ship with dozens of feeds pre-loaded so you can explore the feed "universe" right away. Free readers are available as well; a search for "Feed reader" or "Feed aggregator" at popular search sites will yield many results. A handful of popular feed readers are listed at the bottom of this page.
A typical interface for a feed reader will display your feeds and the number of new (unread) entries within each of those feeds. You can also organize your feeds into categories and even clip and save your favorite entries (with certain applications).
If you prefer, you can use an online, web-based service to track and manage feeds. Online services give you the advantage of being able to access your feed updates anywhere you can find a web browser. Also, upgrades and new features are added automatically.
How can I publish my own feeds?
If you have a website, blog, audio/video content, or even photos, you can offer a feed of your content as an option. If you are using a popular blogging platform or publishing tool like TypePad, Wordpress, or Blogger, you likely publish a feed automatically. Even other non-blogging sites like social photo-sharing service Flickr offer feeds of content you produce that others can retrieve. There are also tools on the market that can help transform traditional web content into the right format for distribution.
FeedBurner's services allow publishers who already have a feed to improve their understanding of and relationship with their audience. Once you have a working feed, run it through FeedBurner and realize a whole new set of benefits.
