Primary Research: Survey Exposure

To give my survey exposure to as many potential people as possible, I posted it to the student notice board, although I would have preferred the course administrator to email my survey as I wanted it to be anonymous, but that is no longer allowed, so this may result in receiving less responses compared to an anonymous post. I also used Pinterest to get my survey to a wider audience, as my postmodernism board has 120 followers, I think realistically at least 10 people may respond, and as my survey isn't aimed at students exclusively I wanted to see if anyone else could respond.
