Feed Rinse is a web-based application that helps you get more out of your RSS subscriptions by blocking posts that you aren’t interested in.

Getting started with Feed Rinse is free and easy:

1. import your feeds (enter subscription url’s, upload opml from your RSS reader, or use the bookmarklet)
2. set up your filters (ie: block posts that do not contain “Web 2.0″)
3. export rinsed feeds (update rinsed feed url’s individually or export opml for your RSS reader)

Your free account will let you set any number of rules for 3 feeds. Upgraded account plans will be ready yet this month to allow you more filters and additional features such as an optional profanity filter.
