The article didn’t really address my pet theory, that for something to increase or decrease in popularity, there has to be some sort of oscillation. Kinkade paintings build negative resonance, and exposure to an artist you like will build positive resonance each time you discover a new facet that makes you marvel. If one viewing is negative, and another positive, well, that just ruins the resonance right there and feelings lessen back to the rest position of “meh”.
