I have been reading Sara Chipp's recent blog post which explained how new users in Stack Overflow are afraid of being judged by multiple people. I think that multiple people telling you how your question is wrong, makes the site seem unfriendly.
Why not hide questions from new users until the question passes through a review in First Posts? That is, until a user reviews the question and marks it as "I'm done" or "No Action Needed", the question will not be viewable to the public.
What it achieves
Since a new user's question will be reviewed by only one person initially, it will be easier for the user to respond/edit without being afraid of being judged in public. It will also give more time to respond / edit before getting downvoted.
