Nick, Vivian, the intention of the wiki was for brainstorming, which allows you to collect the question which to ask in the first place. If you prefer doing this in a survey this is fine, but how do you come up with the questions to ask in the first place (assuming you want to have a collaborative effort which involves multiple participants). This is the power of Wikis, not of our survey module.
Looking forward to the next step (as I think we do have enough information what questions *visitors* of the website will ask the website). Note that this is a different approach than asking what is wrong with our website :).
