You don't have to read everything you're subscribed to. I'll wake up and have, say, 150 or so unread items in my feed reader, and I'll just take 5 minutes or so hitting the next button and marking them as read, and if there's something I care to actually read I'll mark it unread and move on. Then once I've actually found everything I want to read I'll go back and actually read those. A Eurogamer article on a game I don't care about? Skipped. A Eurogamer article about an interview with the devs of a game I love? Mark unread and come back to it after filtering.
