> To be fair, LinkedList is of very limited use. I can't think of a scenario I'd use it in beyond an LRU cache. It's more the point that not knowing they exist is a very strong indicator you haven't read even introductory text on algorithms and data structures. I barely use them either but when I'm thinking of solutions to problems they're a useful concept to know.
