I would like to be involved, but I'm not really sure how. The open source culture and tooling is strictly all about code. At least, that's the way it feels to me. Very unapproachable. And often times, there is zero signal that they would even be interested in getting the help. From my experience.
For what it's worth, I'm a design lead and make six figures. I don't think that has much to do with anything.
