If you’re reading this and have previously read at least one SSC post, please take the 2017 SSC survey. Warning: it’s pretty long.
You can talk about it in the comments, but don’t read them until you’re done taking the survey.
EDIT: Note that a lot of this is going to be processed by computer. That means you should give simple, machine readable answers. If the question is “what city do you live in?”, a simple, machine-readable answer is “Los Angeles”, which easily aggregates into the same bin as everyone else who answered “Los Angeles”. Bad answers would include “I live in Los Angeles”, “Just north of Los Angeles”, “Los Angeles but sometimes in Dallas for work”, et cetera.
