Others want a forum where almost anything goes, as long as it's tangentially related to the forum's subject matter and there are no outright illegalities or blatant flamewars. Think of this like the forestry service. Intervention is only uncontroversial in a catastrophe, like if a non-native invasive species is brought to the area.
I prefer this approach and resent it when threads are shut down because of some moderator’s abhorrence of “thread drift”. I suppose those guys are the neat freaks who love clean desk policies and arrange their staplers and paper clips in rectangular patterns.
