I thought I was pretty clear. The data is garbage, ergo the model is garbage.

This kind of analysis sells because it is like a Rorschach test. People will see a book they know and have some feelings and think that gwern and his algorithm felt it too.

The creation of multiple lists is a good bet on his part because it has more ways to win, lacking an objective criterion for success.

If by "sell" you mean "create a model no one in their right mind would pay for", then sure.
