In this meta question, rhermans showed our current 'How to Ask' sidebar and commented: Current tips seems insufficient.
I must admit that the sidebar had become invisible to me. Now that I have been made aware of it again, I could not agree more. In fact, I'd go a lot further and say I think it would totally confuse me were I a first-time user of Mathematica.SE. I would very much like to see us improve upon it.
The sidebar closely follows the 'How to Ask' sidebar of StackOverflow.SE. I worry that means its content is largely dictated by stack exchange.com, meaning that we have little or no control over it. Is that the case?
Just so you don't have bring up another page to see the current sidebar.
This is in response to J.M.'s comments.
I was afraid no-local-control would be the case. My main gripe concerning the current tips is that they are too concise to convey much of what a new-comer needs to know.
I have posted my sidebar revisions as a community wiki answer as you have suggested.
Edit by J. M.:
As a heads-up: the highest voted proposal by next Tuesday (May 30) will be the one I'll submit to SE staff for inclusion in our sidebar.
