I think you're right when it comes to basic questions (like "how to do XXX in rails"). However, in my practice, 90% of the obstacles are not concerned with how to do something in the framework/language of choice, but rather "how do we do XXX in our code?" (state machines, search, billing, reporting, etc). These questions can be answered by digging into code and understanding the logic, however, it's better if someone senior explains how and why they do things the way they do, clarifies rationale.
