It would be polite to PM the poster about the action, but I can't see much case for having an explicit policy about when to move unless we have clear cases of abuse of this - posts that were moved that shouldn't have been. The point of a benign dictatorship is that the dictator can do as he wants.

Yes. Or, as I have often seen Eliezer do, a comment saying "Moved to Discussion".
Wait. Is PhilGoetz one of the people with whom Eliezer has a professed non-engagement policy?
Yesterday, someone moved one of my posts from Main to Discussion without telling me. Again.
I encourage the site administrators to show some basic courtesy to the posters who provide the content for the site. I believe this would be a better way of doing things:
1. Have a policy on what has to happen to move a post from Main to Discussion. Who can do it? How many admins are there who can do this? State this policy in a FAQ.
2. When you move a post from Main to Discussion, make a comment on the post saying you have done so and why you have done so.
