I think it's more useful to know if they have the problem you have (not whether they think the idea is good). Then, if they do -- what they think about how important it is and if they have tried to solve it. If they have the problem, think it's important, tried to look for solutions (maybe even tried one), then you can find out more about the criteria of the solution they are looking for and the progress they are trying to make in their lives. If they don't have the problem, or if they do, but it's not a big deal to them, then whatever solution you have isn't going to be interesting (so, what they say about it doesn't matter) -- move on to find people with the problem. If no one has the problem, it may be interesting to solve it for yourself (if it is meaningful to you).
