NewsBar
This product works well and is useful in displaying the feeds in three levels, the most detailed being the web page referred to. It seems that it wants you to restart after changing from having the icon on the Dock to being placed in the menu bar but it made the change without my needing the restart. The previous version was good and reliable and the new version seems OK so far under Mavericks.
