If you’re the type of Netflix user who enjoys maximizing the value of your membership, you might find the new website FeedFlix interesting. The service scrapes data from your personal Netflix rss feeds and generates interesting graphs about how long you keep rentals, how many you rent per week, and your cost-per-rental. Sure, you could do this all yourself with a spreadsheet, or maybe Yahoo! Pipes, but FeedFlix is free and works instantly.
