I am trying to answer some severe critics from bryce and mental on my questionnaire:
1. For getting a larger sample size, be sure that I am posting my questionnaire not only on an Inkscape mailing list but also eg in an Adobe forum.
2. I didn't take Scribus, because its targeting mostly people active in print
3. its "just" a survey for my master thesis and it would go beyond the scope to consider all proprietary and OS packages available.
4. science is always distorted and subjective!
5. the questionnaire is only a part for verifying my thesis, I will also use other research methods for getting answers.
6. I am further using ISO 9126, the standard for software testing
7. I am not changing my hypothesis, I am changing the text on the website to sound more neutral!
