You are thinking about how to broaden the appeal of your product.

Consider whether designing for extreme users, rather than just core users, might lead to a product with wider appeal.

1. Draw a graph with a horizontal and vertical axis - make sure to give yourself plenty of space.
2. Think about the one pattern of user behaviour to label the horizontal axis. E.g. "frequency of use". The centre of this line should reflect average usage.
3. The vertical axis will be "number of users". Draw a bell curve.
4. Examine the users at each unpopular end of the bell curve. Why are they acting differently? What is their motivation? Could other people have related needs?
5. Consider a number of different bell curves with different user behaviours.
6. Now ask yourself, are you in danger of building expensive features that are only ever going to be used by a handful of people, or have you uncovered a hidden gem?
