I see where you're coming from there. It's basically a corollary of a recent topic on HN, which was that you in practice rarely encounter a problem that requires you to do anything algorithmically interesting. But then again, if you do, how would you have any idea of how to work on a graph if you couldn't even do a linked list?

I believe that students should work on the ability to come up with data structures that solves different sets of real life problems, and get good at it. If they can do that, then they should be able to easily implement a linked list or graph when they need to.
