There are plenty of good uses for linked list and their variants. Like LRU lists come to mind; I couldn't bet that it's the most efficient way to implement them but they're pretty darn good. Then obviously things like breadth first search need a type of queue data structure. It often can come down to memory pressure, if you've got Gigs to spare, then allocating a contiguous block of memory for a list of something isn't a big deal, if memory is tight and maybe fragmented, linked lists can and will get it done. They have their places. I did start to encounter some fresh grads with degrees that said "computer science" on them that couldn't answer some basic linked list questions. I was beginning to think it was a bad set of questions until I hit those kids. If you claim to know "computer science" and don't know what a linked list is, especially beyond some text books stuff, I'm probably not interested.
