#One time bonus for Nice Questions

This probably won't be implemented. But it seems to be exactly what all you want:

* Easy questions getting a lot of upvotes won't be affected much.
* Questions having a lot of upvotes and downvotes won't be affected much.
* New users writing bad questions won't be affected much before understanding this situation.
* Questions having 10 upvotes and no downvotes would be awarded more.
* Writing many good questions is preferred to writing one extremely popular question, so it really encourages writing questions, instead of posting the idea you had anyway or just being lucky.
* It wouldn't be much worse to upvote the question for the good answers in it.

If changing reputations for upvote / downvote isn't the perfect solution, I'd think it is understandable not making any changes only to revert the changes after problems happen.
