I just learned from AC that there is a "known issue" with the survey. As reported above, when you hit "Submit", the survey does not go through.
About 20% of the time.
And they have not bothered to tell people. In a further indication of how they value our time and our opinions.
If you want to take the time to do the survey, and I would encourage you to do so, you might want to copy and paste your answers unless they are lost when you first submit them. Then paste and try to submit again later. Sometimes it goes through on a later attempt.
