Which of these points was a selling point: -Building a recommendation engine. -Started with general approach, now focused on e-commerce -Cheap/easy alternative to expensive/hard "enterprise" option. (the easy integration part is 'the next step) -Amazon drives 25% ($5bn) of sales via recommendation. They want to bring this to the masses. -Identified: 75% of sites don't have a recommendations, 50% have identified it as something to get. -Already capable of 100s of recommendations per second I guess this doesn't work without the application to fill in the gaps. I felt that the application was missing an explanation why this recommendation engine is good or how it works.
