Sometimes I find myself (even today, as an experienced user) looking at other users posts before I post my own. It helps me come up with better wording, grammar, style and formation.
The Tour pageTour page shows an example of a well asked question along with its answers, and it highlights what should be asked (and what shouldn't):
Unfortunately, many users (most?) don't go through this page, and usually skip it or just scroll down to get a badge.
Since we see many low quality questions that are badly formatted, we can tell that many users don't really care about the "How to Ask" and "How to Format" side bars.
I'm thinking that instead of having wall of text of "How to Ask", we can provide a template* of a good question that has a two paragraphs of a description (including code formation for code-text) with a code snippet that users can take and change for their purposes.
I know that there are many different templates, and many different ways of asking a good question; some might have code, other might only have a description with possible image, it's not easy to have a generic template for a good question - But I'm just dropping the general idea of what I think might help a bit.
Example (of course it should be changed to something more general and make sure everyone understand that it's only a template for demonstration purposes):
This might help newcomers understand basic formation, while it also shows how a good question is asked.
* That template can actually be a placeholder that appears for users with < x reputation points
