Anyone who has been subscribing to RSS feeds for longer than a few months will know your subscription list regularly needs pruning and adjusting. Well, I want my RSS reader to help me with that task. Smart Streams can help by making it easier to wrangle my feeds based on more than just which website they came from. I expect in the long run that they will prove very accommodating and useful as my interests change and as my attention ebbs and flows.

A good overview of Feed Wrangler’s best feature. I’ve been using Feed Wrangler since April and I’m very happy with it.
