I think this was posted before, but it had appeared it was for windows/ jaws users only. I've talked to the person holding the survey, and discovered the initial impression was not intended, so everyone is welcome to fill out the survey. It's not really all that useful in my opinion, but I have o idea what the survey is intended to measure, so have at it.
