I had assumed this survey was for fun - a novelty. But if the intention was to understand the preferences of Head FI members, develop personas or segments (i.e. consumer research), or gather data for some other sales or marketing purpose, then it seems like it was not well designed.
These polling techniques , as I indicated in my previous post, are valid ways to assess sentiment and preference. But like a survey, they must be properly designed for the particular hypotheses they are intended to test, by people who understand how this is done - e.g. folks with consumer research background. And usually, these kinds of sentiment analysis tools are intended to compliment other methods.
Perhaps Jude can clarify if this was just for fun, or to better understand the interests of our members, or something else.
