Google Reader NG Filter weeds out the junk in Google Reader making browsing my news feeds more enjoyable and leaving me more time for the articles I'm interested in.
Out of the many Google Reader filtering methods I've tried Google Reader NG Filter has been by far the most effective. This script allows one to easily remove items in the feeds without breaking other features like sharing or extensions like ReadItLater. The filters can gut junk stories on a broad scale or be tailored for specific news feeds. Regular Expression allows for complete control of how items are searched and filtered out.
