We currently require that new users have 5+ reputation to participate in meta support discussions (bugs, feedback, governance, etc). This is primarily because the use case for meta is not intrinsically obvious, so we require a modicum of "experience" with the site before jumping into it.
But that blocks new users with legitimate questions about their own posts.
Setting aside any arguments about new-users-are-evil-and-suck-the-life-out-of-our-community, I would like to propose a very specific path for new users to ask about their own question provisionally.
Instead of blocking a new user with this message:
You must have at least 5 reputation on <site> to ask a question on meta.
We can change this to:
You must have at least 5 reputation on <site> to post on meta, but you may ask a question about your own post specifically.
Link to your post:
ask about this post cancel
The system will check whether the linked question provided belongs to the author. It doesn't matter if the question is deleted or not.. The user can then proceed with the post provided they leave the template (below) intact:
<!--Do not remove-->
<!--Note: Questions not about your post will be deleted-->
I have a question about the post: How do I get full administrative privileges in Windows 7?
<!-- Your question below: -->
Not only is this a great and gentle introduction to the proper use of meta, but it stands to help new users just when they need it most (learning to use the community).
Of course this doesn't 100% guarantee that someone won't get it wrong on occasion. But this is an awful lot of in-your-face guidance without simply telling people "read our FAQ" (which they never do). And if a user manages to step over all that guidance and still manages to misuse meta, I have no compunction about summarily removing a question they should never have posted.
But this just-in-time learning is a very effective way of learning a new site in a gentle and thoughtful way. If this is abused more often than not, it is easy to disable. But it's better than assuming clueless newbie every time.
