If you're talking about the RFF gallery. I believe an image with strong contrast/clolours and simple forms gets more views. These elements help people discern the image when displayed in its small thumbnail view and will make them more likely to click on it to view it larger. Of course such elements may not ultimately always make for the best image.
I have to agree with that. And would add that even a 700 pixel wide jpeg doesn't do justice to most pictures.
To counter balance your opinions about the public, let me recall the great David Vestal, who stated we the photographers are very bad editors of our images. Why?
Have to ask David Vestal.
When I look at a foggy picture of a hilltop, I remember the 12 h hike; other people see a ruined sunrise pic.
True, but if it is just what you remember about taking the picture that makes it a good picture, it isn't a good picture.
To the original question: Good and popular do not always go hand in hand. Could they even be mutually exclusive?
Cheers,
