Snarfer
Snarfer is a light-weight RSS reader application that says about itself to "provide a new approach to RSS feed aggregation focusing on speed, efficiency and ease of use." The last version was published in 2008 and the project is officially discontinued. Snarfer is still available for download and probably still functional. More from the author's website: "Snarfer includes a Search Wizard that enables users to construct complex searches for items or information contained on eBay or Craigslist. These searches are intelligent and tent automatically returning new results to Snarfer every time the feed is updated. Another exciting feature is the addition of Bloglines synchronization."
