Moderation is the process of eliminating or lessening extremes. It is used to ensure normality throughout the medium on which it is being conducted. Common uses of moderation include:Ensuring consistency and accuracy in the marking of student assessments. A moderator may remove unsuitable contributions from the website, forum or IRC channel they represent in accordance with their moderation system. A more proactive nuance is found in the Methodist church's use of the term for the heads of its conferences. A neutron moderator is used to slow down neutrons in a nuclear reactor. A way of life emphasizing perfect amounts of everything, not indulging in too much of one thing, hence moderation.
Extremism in the defense of liberty is no vice. Moderation in the pursuit of justice is no virtue. (Senator Barry Goldwater).
