One of the easiest ways to achieve what this question seems to be asking for, is the implemetation of some kind of an SE type community bulletin, see fo example the topmost pink shaded (or whatever the color is meant to be) box in the right side bar of MathOverflow. Which meta posts are linked to from this community bulletin, is determined on SE partially by an automatied algorithm based on votes, number of answers, activity, etc (I dont know the exact mechanism), and in addition posts can be made to appear in the community bulletin by adding a "featured" tag.
On PhysicsOverflow, such a community bulletin could for example be implemented in the right side bar for example below the news and above the tools for paper authors. For this solution, it would not even be needed that a new feature has to be developped (except in case the selection of relevenat meta posts to be featured should have an automated component too instead of being done manually only).
Implementing such a community bulletin in the right side bar would have the advantage that the whole community (including members that are almost exclusively active in the science sections) are aware of important issues and discussions that concern the whole community (such as elections, important polls, other moderation related issues, etc). Members who are not interested in any meta issues at all, could still ignore them and would not be distracted too much (depending on the colors used) by such a community bulletin.
