In case you thought RSS was nothing more than a nifty tool for finding out what’s been posted to a blog or Web site, you should know that there are people out there thinking up new ways to use the technology. A Sunnyvale, CA form called Dulance has dreamed up a way to use RSS to help consumers find the lowest price on products and services. According to the press release, “Shoppers with a particular item and price in mind can now initiate a search once and rely on their RSS reader to repeat it automatically, until at least one seller drops the price below the set level.”

In the meantime, as evidence that the prediced wave of RSS advertising is on its way, a company called Pheedo (get it?) “released a new ad serving product that allows bloggers, micro-publishers, and larger media outlets to insert paid ads into their RSS/Atom feeds, and track both ad and feed activity,” according to a Media Daily News news brief.  The product is called Simple Ads for Feeds. At the same time, Kanoodle—a sponsored links provider—has partnered with Six Apart—the maker of Moveable Type and TypePad—to “offer TypePad subscribers the ability to easily add Kanoodle?s content-targeted sponsored links to their sites. This marks the first time that bloggers will have seamless access to revenue-generating sponsored links as part of their publishing toolset. The companies expect the product to be live by the first quarter of next year,” according to a Search Engine Journal news brief.
