Like email, as your RSS subscriptions grow, they can begin to require management.
Strategies for doing so are probably worthy of discussion. Some examples:
I’ve currently been updating my feeds but haven’t really settled on a preferred approach of my own so…
I’m curious to hear other people’s feed systems!
I’m currently subscribed to 12 feeds, most of which post once a century. I don’t.
I don’t have as many these days but I have a hierarchy roughly like this one:
The news category by far gets the most activity, nothing else updates fast enough to be a problem, so everything else has notifications left on
I use two different categories: “Awesomes” and “Extra awesomes”. Every feed is awesome (otherwise I simply wouldn’t subscribe) but the latter category is for people with which I’m personally acquainted to some extent. So I try to see what they are up to first.
Additional coping strategies includes a liberal use of “Mark all as read” whenever I’m feeling overwhelmed. It’s a great way to challenge my incessant fomo 
I am subscribed to 20-ish feeds and they are all lumped under “Personal.” Some post A LOT (like kottke.org) and many others post once in a blue moon.
@Nanoroar - I admire your sorting!
I like this!
I’ve implemented a “three (3) strike policy”. If I personally don’t enjoy reading what I’ve received from a feed 3 times in-a-row-ish, I remove it. Easy to keep tally-mark track in a text file.
