Criticker vs Netflix
Criticker claims to be "the best Movie Recommendation Engine and Community on the Internet!" When asked if they would be trying for the NetflixPrize, their answer was "NO ! We won’t take part...if someone ever tries to submit our algorithm, it won’t do him and Netflix any good - because Netflix won’t be able to use it.
To get our algorithm they would need to buy Criticker, but it won’t be a 1 million [dollar] bargain."
Have you tried Criticker? If so, how does it compare to Netflix?
