Let Hot Pages Cool is a Wiki editing guideline.
Context
Wiki Wiki Web pages can grow very quickly. That can be a good thing (e.g. Brain Storming). However, Thread Mode argument often generates More Heat Than Light. Such pages can degenerate into noise.
Therefore, let hot pages cool before contributing.
Wait a little while. Write your contribution in a text editor and hold onto it for ten minutes, an hour, a day or maybe a month. Wiki lives in the Long Now. After that, come back to the page, reread it, and decide whether your contribution (a) still merits adding, (b) hasn't been said by someone else, and (c) follows Good Style. If it satisfies these criteria, post away.

Dealing with Insults
Let Hot Pages Cool, or something similar, is also recognized at other sites like Wiki Pedia. The link at en.wikipedia.org 
has good advice for people who perceive they have been targeted for unwarranted insults.
There is "hot" in a conversation that's progressing rapidly, and there is "hot" in a heated argument. I think the two are different, and that Let Hot Pages Cool applies to the former while Cooling Off Period is more suitable for the latter - it's not the page that needs to cool, but the authors. Asking people who need a Cooling Off Period to Let Hot Pages Cool is unlikely to make much difference. Mix or split the concepts?
I've found that this has merit when contributing to cool pages, too. The time between writing and posting reveals the gap between what I want to say and what I almost said.
Letting hot pages cool also gives others a chance to contribute.
Most wikis have a "minor changes" button that keeps discussion threads off Recent Changes, where they might pick up additional combatants. For this purpose, Japanese-stype anonymous BBSes like 2ch allow you to reply to a thread without bumping it to the top by typing "sage" in the email field.
