RSS Digest fetches items from the RSS or Atom feed that you specify and posts them to your blog in a daily or weekly digest.
A common use is to create a daily digest of items you’ve posted to social networking sites such as Delicious, Twitter, Facebook, etc.
Unlike the other couple of WordPress plugins providing similar functionality, RSS Digest features a settings page for easy configuration. (No editing code… Yay!)
