I don't see how the survey is tied to our LW username. I think he just means that he will publish the whole of the data. Yvain's survey didn't even include usernames, it just had karma that might identify specific users. This survey doesn't even have karma.
This is correct; I have no intention of publishing usernames, nor could I, had I such an intent.
Some have been curious about what the politics of this community would look like if broken down further; here's a shot at figuring it out. I've also included a few other questions that folks expressed curiosity about. Aside from one sensitive question, there's no option to keep your answers private, since in my opinion that would defeat the point - just don't answer if you have concerns - but there's also no overlap with the old survey, aside from asking you how you answered the original politics question. (This should help with interpreting those results even if the n for this is much lower than and somehow biased relative to the big survey.)
For entertainment purposes only, don't use the below space to discuss politics directly, &c. Early suggestions are likely to be incorporated, given what I assume to be the low quality of the first draft.
Edit: "left" and "right" operationalized for the questions they appear in; poor language cleared up in mental health question.
Edit 2: results here; see comment below for some preliminary thoughts. Because there were several unique regional responses, I did not publish responses that question.
