LinkedIn for Business makes LinkedIn much more than Twitter in respect to product offerings and in terms of support, marketing and sales as those are much more important when dealing with business customers. All of those products need to be developed, supported, updated, etc. The teams doing that however also need to be managed, so additional HR, Managers, etc. I think it is just that all of these different departments quickly add up to quite a significant amount of people.
