I’ve gathered quite a few feeds over the years (including a migration from the dear, departed Google Reader).
I usually keep my view to find only those feeds that have new content, but I’ve gathered a lot of cruft. I’d like to find and drop those feeds that haven’t had a new post in, say, a year or so, and drop them.
Going to each and every feed to do this is not the preferred way to do this.
Is there a way I can find old and abandoned feeds?
