I would say that cotinuations In the sense of call/cc are overused. You have to look hard for a problem where undelimited continuations are in any way better than delimited ones. For the vast majority of cases, delimited continuations are faster, use less memory (and makes garbage Collection easier) and are generally easier to reason about.
