Aesthetically pleasing. Rated 5 out of 5 stars

Sage makes it more comfortable to read the feeds from its page than actually going to the original websites.. It's fast, easy to use and as far as I know from a year of experience with it, it's also free of any apparent bugs. Probably the best rss reader there is.

This review is for a previous version of the add-on (1.3.10).
