Here are some obvious signals that I think can be pulled from the data set:

• gender

• age (since they just straight up ask for it)

• rough geo data (if the survey records IP geo information, so assume they are doing that)

• economic status

• rough tech literacy level

As far as I know, it's not possible to record respondents' IP addresses with Google Surveys, so I think that one's out. I suppose you could make rough inferences based on the food, weather, and snow questions.

The keyboard part will help quite a bit, at least. Being from Norway, the occasional æ-ø-ås are quite revealing.

I type on Dvorak, so lots of "oeuieu" (clusters of vowels) in there. Midway through the gibberish I typed "this is a dvorak keyboard" just for grins.
