In my quest to find good places where to post links to my survey, I happend on gamesforum.com, which I recommend for discussions, but not for posting research questions! I posted without reading through the entire board, and the administrators received my post in a friendly manner - but noted that I'd probably not get a lot of replies, as they had been flooded with surveys lately. That's when I started reading.
If you're interested in seeing what kind of research questions the coming generations of researchers are asking, check gamesforum.com! There they are, the links, and the questions and the presentations. Finland and California, the games researchers unite in the search for good respondents. It's quite amusing as well as, of course, an extra challenge to getting my respondents. And it gives me an idea about what kind of questions students ask.
