As a design engineer, when I see major design changes that I don't understand, the question I usually ask of a team is "what problem are you trying to fix?" or "what user need are you trying to better address?".
The recent increase in question upvote score has sent me down the path of asking that question. I think I can feel a problem that needs solving behind this change, but I'm not quite sure of what it is, and I'm not quite sure that the implemented change would fix some of the things I imagine them to be.
So, in the interest of moving forward, I suggest that somewhere in this mix is the need for more and better questions, mixed up with the need to retain users.
Toward this end, I suggest encouraging people to ask better questions by implementing a badge that would be rewarded when a user rescues their own question, either from an initial spate of downvotes or close votes, or manages to get it reopened, by a good edit.
I think the message it sends is "Thanks for working to improve your question. This is behavior we value". I think it might be a mitigator for hurt feelings after a poor first attempt of asking a question of a community, i.e., a "no hard feelings" olive branch.
