I posted a question on Stack Overflow and it was soon closed as off-topic. My question is why was it closed as off-topic? Especially since to my understanding, it's "a question about software tools commonly used by programmers". I understand it's just how SO works, so no whining from me, just being curious.
Additional bonus: I see there are many people here on Meta asking just that. Wouldn't it be convenient to place a small explanation when voting to close a question, visible to the OP? (Like the comments when editing)
