I will don't understand why it's called Poe's Law if he said it in 2005. This phenomenon was well documented on Usenet by the early nineties.

If we called everything that was first described on Usenet as "Usenet's Law" then everything would be Usenet's law, probably even a couple of things in physics.

Poe's Law is when extreme views seem to self-parody. That's different from someone missing the joke on mundane sarcasm.
