Like this one: 'Looking for a hardware project idea that actually sells'.
A question that asks essential "I need ideas... go!" without any background, or qualifications, or criteria, or anything is--as you say--just being chatty. It's not a good question.
The answers suggest that there could have been an interesting question in there somewhere but the answers don't match the question. That supports attitude that it is a poorly-conceived question: the answers don't apply because the question is too vague.
This blog post, while not directly applicable to this case, might be helpful in routing out "bad subjective" questions like this.
