> So either this is a small win in frontend efficiency, or continuous scrolling is fast enough that a large fraction of users goes past the initial set? Yeah, it doesn't really make sense. Infinite scroll is pages tacked onto each other in the frontend - the backend should be doing the same amount of work for page X, except less overall because it's not returning the header/footer. I don't think frontend efficiency works either because the first page of results should be the same - or, possibly, the tiniest bit more work because now they have a footer to return as well.
