Unless and until we can recommend things that aren't available via netflix, this invention remains another crowdsourced, yet ironically still proprietary, commercial product. Nexflix already had my viewing habits, my daily routine, and my money. They shouldn't need my help too.
Netflix needs/wants in-house recommendations because any external recommendation service risks drawing attention to their limited offerings. Netflix has around 20,000 titles for Americans, closer to 6000 it seems for canadians. That's only slightly better than a well-stocked blockbuster video. Nearly every old show recommended to me by friends, by actual flesh-and-blood people, isn't there.
Also, What happens to recommendations once the shows they recommend are dropped from the netflix lineup?
