I recently asked a question about getting an annual survey similar to the official developer survey. The current consensus to this is "unlikely".
Following that Oblivous Sage asked if we wanted to make our own. To which the current assumption is "yes but what would we ask? and who would make it?". I will leave that question to deal with who is actually going to create the survey.
This question is to serve as a gathering post for the questions we want to ask. Highly voted responses should reflect what the community is actually curious about.
