Seriously, how do you keep up with all these super interesting newsletters and articles you receive/see around every week?

I tried keeping them as unread on my inbox so I can read them later. I tried sending them to Instapaper or similars. But it's always the same, the list keeps growing and growing until I remove everything and start over.

How do you organize your out-of-control reading list? Is there a service capable of filtering what I'm really interested in based on what I really read? Where are the algorithms when we need them?
