I noticed after one code submission that the site asks me what do I expect from it. The multiple choice question only lets the user chose one answer, which I find sad since I expect more that one of those suggestions.
Additionaly, you could IMO link a more detailed survey to let the user decide if he wants to gove you more datas.
I understand it. My point was just :
1- Giving more than one possible answer might not be more intrusive than limiting to one
2- If they are currently interested in feedback, I think a lot of us are ready to take some more time to give more in-depth answer.
