I enjoyed what this guy had to say, too, but I was curious about what he is going to do for facebook. For that matter, what AI can do for facebook. The closest I could find was this:
Facebook can potentially show each person on Facebook about 2,000 items per day: posts, pictures, videos, etc. But no one has time for this. Hence Facebook has to automatically select 100 to 150 items that users want to see -- or need to see.
I thought the whole point of facebook was to keep up with your friends. *shrug*
