- Give users a view that ranked their question examples by the number of NaGE votes received (cf. Add “not a good example” to my profile proposal), and
- Let reputation be immediately recovered from NaGE votes on deletion of questions.
This would, I think, both encourage the withdrawal of weak question examples and encourage more application of NaGE votes to weak questions. If both these things happened, then the list of question examples would correspond more closely with the list of question examples deserving consideration.
