It seems that users have spoken and that recommendation systems are a feature, not a product. On the web, this means that recommendations either need to be 1) embedded in a consumption experience, the way they are on Amazon or Netflix, or 2) attached to a discovery mechanism, which (usually) means SEO’d via Google a la TripAdvisor and Yelp.
I learned this the hard way at Hunch. Ultimately, it was obvious that the best use of our technology was to embed it on eBay. I’d be excited if a standalone recommendation system succeeded, but until it happens I’m skeptical.
Dang. I respect Chris’s directness.
