Online classes: who takes them, and why?

I conducted an online survey, of students in my GEOG 413 class, which is completely online this fall term.
I kept it very simple, because I did not want to bore the students. At the same time, I wanted to get some key information, so that I can correspondingly massage my course structure. The summary of that survey follows.

Note:
I had embedded into the class homepage a survey that was actually through polldaddy.com, where I developed the survey questions.

What I find interesting:
A majority of the students have never had me as an instructor. So, it is not any “familiarity” that drew them to this class.
For ten out of the 25, this is the first online class ever.
Only 13 out of the 25 are confident that they would have taken this class, even if it were not online.
