Something that jumps out to me in the demographics is how few respondents are from Japan (0.6% vs e.g. 5.1% from Germany). Does anyone have a good explanation?
We are primarily English speaking (myself being European and working in the USA now) and they struggle with English immensely, in general.
Many projects from Japan that I see have faulty English grammar in variable names and is documented only in Japanese characters.
It seems to me they mostly targeted English speaking countries, which would explain why Japan (and Asia in general) has such low response.
But I agree that The Netherlands has a pretty big development community, and generally their English is fairly close to being native.
