I am interventionist.  If something is wrong or someone is behaving inappropriately I deal with it, often publically.  I have deleted posts, whole discussion threads - taken away people's posting rights, and even taken away moderation and admin powers.  These actions are usually accompanied by a private message to the involved parties, explain what I did and why. 

Dom on the other hand tried to nudge people in the right direction by posting with them publically.  He behaves like a 'regular' member of the board and tries to reason, in the context of the discussion or, as if often the case, argument.  He will at the request of another member delete offensive posts.  But it is always in response to complaints, and never because his own sense of (in)justice prompts him to take action.

At work I am the academic manager and my senior teacher is a guy called Manjit.  I manage people at work in a similar way to how I manage people at The Northlands.  I deal with them directly, getting to the core of the issues that are causing inappropriate behaviour.  I talk to teacher x about his anger, and teacher y about her depression.  I tell them my concerns about how I percieve it is affecting (or may affect) their performance.  In cases of extreme underperformance I give people the chance to change and if they don't I put them on a perfomance plan, take away a post of responsibility or in extreme cases ask them to leave.

Manjit is like Dom, much more subtle.  He manages underperformance when has resulted in a complaint from a student or some other concrete outcome (i.e. a covering teacher hasn't been able to plan a lesson because the main teacher hasn't completed their admin fully).  He will grumble and worry, but he will not hand the teacher the responsibility for changing their behaviour until he has external evidence which he can take to them and ask them to explain, justify and ultimately correct. 

It is easier to reflect on the actions of others than oneself but if I were to try and analyse these different management styles I would say I see myself as a guardian of the people whereas Dom and Manjit are guardians of the process.
