I really liked this survey. I don't think it was too long and I got a vibe that it will really be used for something useful for these reasons:
- The questions are formed around topics heatly discussed on these forums and bugreports.
- A few questions were asked twice. They do this to see whether your answer changes after being influenced by other questions of the survey. What conclusions exactly they can draw from this who knows, but there's a reason for them doing this I'm certain.
- The offering of fields where you can specify what you mean and question forming is thought out to appease whatever you might want to say. For example in the freeword bit where you are welcomed to give among other things "improvement suggestions".

Haha that sounds really cryptic now that I said it, but I just mean that I think our answers are really going to have an effect!
