Why is this being downvoted?

The question is pretty legit; the long application asks a number of questions like how much you use desktop apps (Anything from MATLAB to Citrix), and also about your preference in Google products vs anything else (gmail, calendar, docs, etc).

Is there any indication to whether they are picking people with good fits (e.g. those who basically use all the Google products already) or are they just selecting people randomly, using the data provided just for stats and context to the person's inputs?
