Learned this one the hard way. If you ask the equivalent of "what could I add to make this more useful?" you will get a lot of worthless suggestions like "I don't know, maybe make it sortable by the other column, too?" that don't move the needle at all on engagement.
As has been said before: Users are almost always right when they say a problem exists; but they are almost always wrong when they suggest a solution.
I think the point is more that _not_ talking is even more misleading.
