I think the term that I would use is "serious". Of course we're serious about the quality of our product. However that can involve plenty of stress and burn-out. We deal with a lot of serious issues: conflicts of interest, harassment, finances, legal compliance, reliability, privacy, safety, and more. My personal experience is that there's little gratitude for good work, and lots of complaints when things go awry. I would like to see us foster an emotional environment that's a bit on the brighter side, and would be interested in others' thoughts about how we can do that.
