For very massive browsers such as the sauropods, a long neck makes sense to me in terms of energetics. A long neck, which allows the animal to vacuum up biomass over a large area without moving its entire body, would have tended

Well, a large arc anyway. Depends on how flexible that neck is.

to increase the time spent feeding and decrease the time spent moving from one feeding location to another. Moving from one feeding location to another is more energetically expensive than standing in one place and eating. Not only does it take a lot of energy to move 50 or 100 tons, but it's likely the animal wasn't actively browsing while moving to a new location.
