This is awful advice which is based on a complete misunderstanding of the use cases of linked lists. Linked lists apply in situations when you can't place things in arrays (because they are too large to copy, or because there will be pointers maintained to them). The author makes much ado about locality of reference and cpu friendly layout without understanding that those things are irrelevant because this is a data structure to use when indirection is required. It always amazes me that such simple data structures can be so poorly understood.
