Godwin’s Law: There’s so much about the Internet that I don’t know yet.
Godwin’s Law (also Godwin’s Rule of Nazi Analogies) is, in Internet culture, an adage originated in 1990 by Mike Godwin that states:
As an online discussion grows longer, the probability of a comparison involving Nazis or Hitler approaches one.
There is a tradition in many Usenet newsgroups that once such a comparison is made the thread in which the comment was posted is finished and whoever mentioned the Nazis has automatically lost whatever debate was in progress.
I don't like the idea of this 'Godwin' trying to exercise control over what sorts of analogies I use. It's like he's the Hitler of analogies or something. ;-)
Then there's the corollary that says you cannot intentionally invoke Godwin's Law to end a thread. I can't find a reference, though.
Darren -- it's in that Wikipedia article:
"It is considered poor form to raise arbitrarily such a comparison with the motive of ending the thread. There is a widely recognized codicil that any such deliberate invocation of Godwin's Law will be unsuccessful."
