Removing RSS feeds that haven't updated in a certain amount of days(google reader)

Question

I use Google Reader to keep track of my RSS feeds. Over the past couple of years I've added a lot of feeds, and I've noticed some just don't update anymore.

I'm looking for a way to remove feeds older than a certain amount of days. Are there any programs out there with this functionality built-in? Or does Google have this function and have I just missed it?

Answer 1

Here's the manual work-around:

While in Google Reader, click "Trends" up towards the top left of the page. Under Subscription Trends click on "Inactive". There's what you're after -- just click the little trashcan icon to remove the ones you want to dump.
