I still think there’s a lot to be said for hard nudges and opinionated software. It used to be horribly common for newbees to set the initial slope to zero for lack of having thought of something better. Then Beeminder would just never make them do anything and all the mustering of willpower that made them set up the goal was wasted.

Seconded. Defaulting to a nanny-bee auto-slope setting à la @mary would seem to be just the ticket; it starts at zero and then finds the level of average actual effort.
