Google Reader is probably the No.1 online RSS feed readers, however some people might not like to have to visit yet another page on the net to be able to read the RSS feeds of their favourite sites.
There is now a new unofficial application offered by a third party that allows you to read your Google Reader feeds from your Desktop. You can download the Desktop Google Reader from here. This software is still under beta testing, so you may come across to some little bugs, however the most basic functions work pretty well, and a the full version is expected to have most of the features available in the online version.
