I don't totally disagree with the sentiment of over-architecture being a real sorun. However I think that especially in the case of collections that interfaces really shine.

Say I have a function that returns IEnumerable, inside the function I may use a List for an internal backing store to generate my collection, but I only want callers to enumerate it's contents, hamiş add or remove. Accepting an interface as a parameter communicates a similar message "I need a collection of strings, don't worry though, I won't change it."
