Hello everybody!
This is Arne, and first up: A BIG thank you to everybody who has participated already!
The response has already been great! I certainly know my way around a computer (it's not like I would be working for Tom's Hardware otherwise

), but there are already so many things I would never have thought of in those answers. When I set out to do this project, I wanted to be the first one to base this kind of questionnaire on input from a group of actual experts, because I thought that it would make a huge difference in the variety and quality of the questions. It looks like this is even more the case than I thought!
To those who have commented above (and those who wrote similar things in the comments section of the questionnaire): The previous literature has always just made the distinction between the three levels (novice, advanced, and expert). Based on your feedback, I am already thinking that this might not be enough, and another category might need to be added above expert. If you would like to comment further on what that one should include (and what to name it), feel free to put it in the survey again under the comments section (if you have already taken it, just take it again and only fill out that section), or you can email it to me.
A number of people have already asked about seeing the results. I will ask Chris about that.
Again, thank you all so very much for this!!!
Best,
Arne
