Marl is the marginal user. The one who represents the broad base of users that drive most product decisions to the lowest common denominator. Attention is short. Intolerance for change is high. When you ask why they dumbed down your favorite consumer app into a sugar coated dopamine factory, it’s probably because of Marl.
We’ve all been Marl at one point time or another.
The thing people forget is that we are all Marl. The things we think couldn’t possibly apply to us, what we think is designed for a mindless scrolling drone, is us too. We are not always Marl and some might be more Marl than others, but we truly are that way some of the time.
