Unfortunately SurveyMonkey isn't best suited to gathering consumer feedback. The best examples I've seen have been Innocent Smoothies (throw your empty bottles in one trash can or the other to give your "response"), and the taxis here in Dubai, which have a 5 question electronic survey on the back of the drivers' seats. Go for the win and put the survey in a public urinal and have people "respond" by peeing in one direction or another.
In my experience posting survey links in facebook groups has brought out better response. And I am talking about formal surveys in targeted groups like open coffee club, location specific geeks group etc., in our context.
Could we rework our survey and go out to who we believe are our target market? Or do we need to go a further step and just present the problem to anyone for initial validation?
