Excellent Idea but...
But the first thing that comes to mind, for me, is that The Mayor is postponing his monthly treatise because he has more important things to do with his time.
Reading through a bunch of other-peoples stuff and evaluating it would take more time than writing a simple essay.
If The Mayor decided to appoint a trusted source to write a guest Podium, then that would be good.
P.S.
Your caps lock is on.
