We probably all agree that when a new user gets into trouble - seeing their question downvoted or closed - it's great if someone experienced leaves a verbose comment explaining what went wrong, especially if it's a good-faith user who isn't yet quite grokking SO's culture.
Such comments can't be expected - it's impossible to provide custom-tailored help for everyone at 7k+ questions a day - but it's still nice when it happens.
What about designing a review queue specifically to point at cases like these? Obviously as a pointer for experienced users who don't mind providing helpful comments.
The queue would try to find questions from users that may need such help. Possible specific criteria include: Questions....
... that are the first, second or third question from a new user
... that are getting downvotes (net -1 or lower )
... and/or closevotes (2 or more)
... and have no upvoted comments (a polite, verbose comment usually gets upvotes)
... or have had comments with at least one offensive flag (pointing to a possible "user is getting flamed" scenario where a calm voice may make sense)
that have no spam flags (spam just needs to be destroyed)
An additional metric that might be possible to use is the maximum length of comments present in the question. Helpful comments usually tend to be a bit longer - although I have no idea how reliable this would be statistically.
Would this make sense in general?
