Get acquainted with jp FeedMe* here.

jp FeedMe is an Ajax-based RSS feeder component that integrates with Feedgator to bring funky-fresh content to your Joomla site. You can present RSS content based on keywords you define and organized by age and source. FeedMe looks for new content on a set schedule, so your readers will be transfixed at your site, powerless to tear themselves away from all that content. 

But don't take our word for it. Go play with it now! (Not too much, or you'll go blind.)

  *It has a nicer ring than "Ajconviwer JP," don't you think?
