Forgive my questioning of your project, but if your going for an IT degree, shouldn't you focus your paper on the types of pages/servers/software rather than what would influence a buyer? That to me sounds much more like a psychology paper. Maybe the types of forum software, security, platforms they run on? Maybe I'm off base and I'm sorry if I am, but that seems to make more sense in an IT type environment. Content of the page is important, but that is left to the web designer rather than the guy who has to maintain what they run on, unless your goal is to be a web designer?
