I currently subscribe to 121 feeds. A few days my number was 153. Missing even one day of reading my feeds with 153 subscriptions can be time consuming. I only want to subscribe to those blogs that I'm truly interested in. I don't want to waste my time reading content I could careless about. It was time to unsubscribe to a handful of blogs.
I still think 121 is a bit much, but there are quite a few blogs that I subscribe to that don't update frequently, but when they do, I don't want to miss out. It takes me about 30-45 minutes a day to go through my feed. That's a lot of time now that I actually think about it. Perhaps I need to clear out more.
