I have over 200 subscriptions in my Google Reader and I'm reading almost 300 RSS entries everyday. So my problem is to determine most powerful sources for me. So what I need to see is the statistics of my sources. Like daily activity, weekly, monthly.
Also, I want that tool give me my likes, shares based on sources. If I'm not liking or sharing a source, I assume that that's not a valuable source for me, and I want to unsubscribe from that source. So when you have 200+ source, it becomes hard to do it by yourself.
Is there any tool/service or way to do this?
