I pick things from the bottom of the list a lot. I really hate when engineers try to guess what I want. I already know what I want. These “automatic” products are terrible.
What do you think is a good list length? One can assume search results are practically infinite, so you have to make a decision of where to stop. What would your heuristic / algorithm be for determining the termination point?
I did a test, searching for a pop song. I got 9 results for that pop song and then the "People also watched" section comes up. After 4 results with a +6 more button, it goes back to my pop song results.
