Writing Semantic Markup
"The biggest and most welcome change on the Web in the last five years has been the astronomical growth of Web feeds: XML files containing a snapshot of a Web site’s newest content that saves readers a tremendous amount of time. In 2000, there was only a handful of feeds. In 2005, there are millions.
In Web 2.0, the Web as platform, Web feeds are a simple way to share and receive content. If we think of a Web URL as a really simple interface for requesting information—a simple application programming interface (API)—then a Web feed is the simplest responses we can receive. We type in a feed URL and receive the content that is there—usually the last 10 items added to a Web site.
The hard work that RSS does allows us to keep up with many more Web sites in much less time. But it also allows us to share information that we weren’t sharing before, allowing others to remix our content in new, useful ways.
RSS, or really simple syndication, is one type of Web feed format. Its adoption by blog software vendors and major media outlets has created an amazing efficiency in the way that we use the Web. Instead of having to browse to our favorite sites over and over again to see if something is new, we can simply subscribe to an RSS feed with any feed aggregator. There are Web and desktop aggregators that periodically poll the sites you’re subscribed to and notify you if something is new." continued ... (Via Digital Web Magazine)
