A couple of things.

First the easiest way to get them to take the surveys is to keep it simple. A lot of the prgressive cities are now using this format but they only ask one or two questions at a time.

Some of your questions could be recognized with programs that monitor usage as "webtrend, webalizer, etc.."

(How do you find this wesite to navigate?
Is the information contained within this site what you were looking for/needed/expected?)

Any content will offend someone. A lot of people go to sites of Faith. A lot more go to Adult Sites, including most of the major corporarions in America to learn from thier money making ideas.
(Is there anything in the content of this site that would put you off coming back?)

Regarding what they want to see, you could offer something for recomendations or submissions.
(What would you like to see included?)

People will take any survey if it is fun or rewarding. I have a page at www.Modernchild.com that is a survey. It has eight questions about "ARE YOU MARRIED TO A NERD?" I use this survey to help direct traffic to my sites. On average 900 people a month fill out the survey completly and hit the submit. They are then sent to another page that rotates weekly.
