Serious laughs. I once bought a ping-pong table on Amazon and received recommendations for other ping-pong tables from them for months. I think that's what happens when you let robots take over all core competencies of your business. :)

I think it is a great engine for books. "You like books about ping pong? HERE'S A DIFFERENT ONE!"

It's one of those cases where the formula doesn't really work when you expand the scope of a project to handle different cases. Scope creep strikes again.
