My first idea would be a closer service integration on /r/ethereum subreddit. There is a user base of around 10k subscribers and 100 average users online.
It could be designed like follows:
Coordinate with subreddit moderators whether such an integration would be welcome on /r/ethereum.
Setup some RSS-Reddit-Feed-Bot which automatically ...

Most of the problem questions have been closed, and I think the problem will go away with time.
Another idea would be a twitter integration into the #ethereum hashtag. It's the main tag for ethereum and contains around 15 tweets per hour.
We could setup an RSS-Twitter-Feed-Bot which automatically crossposts links from new questions on Twitter.

Regarding the guidance-box on the right when asking a new question: This feature you suggested already exists, if I understand you correctly. As soon as you insert a title and add tags and a body, ...
Edit, nevermind, we just entered public beta!
I don't have the feeling we have an issue with (missing) users yet. This is actually an advantage during the private part of the beta stage.
Now we have to focus on:

3 high quality answers per question, to keep the answer rate above 2.5 (count: 25 ...
Just downvote them, and if the answer is also full of typos or intelligble, flag as Very Low Quality. When users get downvoted in a large part of their posts, they get locked from answering automatically.
There's also probably a way to ping users who "committed"?
