I'm assuming most blog readers are already familiar with Godwin's Law. But in case you're not, the official definition:
"As a Usenet discussion grows longer, the probability of a comparison involving Nazis or Hitler approaches one."
Further explained:
As a Usenet discussion gets longer it tends to get more heated; as more heat enters the discussion, tensions get higher and people start to insult each other over anything they can think of. Godwin's Law merely notes that, eventually, those tensions eventually cause someone to find the worst insults that come to mind - which will almost always include a Nazi comparison.
But wait, there's more:
When it happens, the thread is going to start either degenerating into a long flamewar over Nazi Germany or about Godwin's Law. Either way, the thread is effectively over, and you can safely killfile the thread and move on.
How about we initiate a Godwin's Law of Campaigns?
"As a primary campaign grows longer, the probability of invoking imagery involving Osama bin Laden or 9/11 approaches one."
Then by old school online community rules, the campaign that goes there first loses; we get to declare the contest effectively over; and - best of all - we can finally move on.
