In a lot of ways I really like recommendation algorithms, regularly I've had youtube recommend a video that's converted into new sub (eg. LiamTronix and his electric tractor conversion).

What we really need is "responsible" recommendation systems (that allow the joy of discovery while aggressively damping rage bait and extreme view points). They'd need to be trained with some kind of socially beneficial reward function rather than pure engagement or advertiser dollars.

Could such a recommendation systems operate on top of existing social graphs?
