I didn't, to be honest. I'm not saying they are not appropriate but I'm not a huge fan of those questions. As you said, anyone can Google the answer and I bet many who answer them do.
I'm more for those questions that require life experience, those you can learn from. Someone telling his/her own experience can help others, maybe someone is going to use it some day. We can all copy the question and paste it into Google search box.
I used to avoid them as I saw them as spam. Most of those were the same question changing a few words around and they flooded the place.
Unless we are medical students or doctors who would know and answer them. i am not going to go and Google answers and spend hours answering one question. If that person was serious which i don't think they were then they can go and google it themselves.
I think someone found another site and just copied previous questions as there were just too many similar types of questions. Lets hope they don't come back for a repeat session.
