That, is you can read your feeds as they are updated in real time, as well as creating and renaming folders at will. And the Google Reader bit comes in because it is all synced with Google Reader by default. Any change that occurs while you are using Gruml is reflected on Google Reader, whereas anything that you modify when using Google Reader is translated into Gruml.
Other functionalities include the ability to tweet articles and also shorten links from the main dashboard, whereas Snow Leopard support has already been thought of and taken into consideration.
