Netflix and feature creep

Nothing is purely additive unless everyone uses it:  If there’s an affordance to use a feature, the affordance is a distraction to everyone, while the positive value accrues only to the users and potential users.  The net value of a feature is the value to the users of the feature, divided by the distraction of the affordance to everyone.  Advanced search ends up being used by such a tiny fraction of users (sub 1%), that it can’t possibly pay for its cost.
