Caught Up

So I’m finally caught up on my blog reading. After being on vacation for five days, I had over 500 unread entries. Read some, marked most as read even though I hadn’t. This problem is going to only get worse as I find more interesting blogs to read.

What I want is for my news reader to suggest to me which of my unread entries I am most likely to be interested in. The question is, how to rank all the unranked entries?
