• jumbra.com - Combine all your personal RSS/Atom feeds into one!
  Use jumbra to share your feeds from other sites with everyone. Instead of dealing with many feed URLs and having people subscribe to each one, you can combine them all into one. Others will see everything from your other site feeds... and best of all, you can add new feeds to your list and your combined jumbra feed will update automatically!
