Via Andrew Sullivan, calculate the answer here. I find, however, that this service does not capture the value of Netflix to me. What I like about Netflix is that I can put a movie directly into my queue and then forget about it. It's more a way of organizing information than a means of economizing on movie rental expenses. But why not just set up a tagging system? With Netflix, I feel some financial pressure –or should I say the desire to avoid feeling like a non-maximizing idiot? — to work through my queue at a positive rate. It keeps me watching, or at least trying, more movies than otherwise would be the case.
