The 'pull/scroll to load more' interaction is dependent on there already being enough content to where the user would have to scroll. Does this mean that the amount of results on any given 'page' is also dependent on the height of the results being greater than the height of the viewport?
My question is this: How is this problem most commonly solved? Especially in cases where user's screen is so tall that you would have to spend additional time retrieving a longer list of results for the user? It seems to me that this is a problem that could easily break this interaction, though I see it used many places.
