AideRSS helps to filter and rank these feeds based on a number of criteria to help you read what matters, ensure that you find the good stuff, and to help keep things organized and manageable. With this service, you will have to enter the URL of the feed that you would like to have filtered and they will do some math and checking around the web to learn about this feed, its statistics, and people's reaction to it. Then to the feed, they will assign PostRank^TM scores to all articles in the feed and provide you with a variety of tools to sort and parse these items of interest into manageable lots for you to scan and digest at your leisure.

You can use AideRSS to evaluate a new feed you are considering subscribing to and you can also aggregate your feeds in the My Feeds section to use AideRSS to help you manage, rank and sort your feeds.

PostRank^TM is a scoring system that was developed to rank each article on relevance and reaction. It is a core part of the AideRSS engine that works to ensure that this digital assistant is helping you to tame the RSS beast and keep your news stream manageable.
