+1 on the above. I never saw the draw of Viigo. It's an incredible performance drain and is unnecessarily huge. Although I don't have a wonder-app to suggest instead. Haven't tried Arr!SS yet, as upvise and the native BB browser do well enough to cover my RSS needs.

Arr!SS is ok, but since you have to launch the browser to read the full articles it isn't quite as useful as it could be. After using Viigo daily for more than a year I have switched to FreeRange, which has been great. It is quick, has a small memory footprint, is very customizable, and renders full articles in the app and better than Viigo (you can follow links if you have multiple page articles).
