I'm really impressed that NYT took the time to document this. It's always interesting to see the different recommendation models evaluated and applied to real-world situations. I've been pursuing a collaborative filtering approach to product recommendation lately ('people who bought this also bought that'), but perhaps LDA would let me model our products based on their metadata ('people who bought products broadly like this also bought products broadly like that').
