I was recently reminded of Mike Godwin’s law from analysing discussion groups end of last century (yes, that for many of us were the nineties … when we all started using the internet for the first time). Wikipedia summarises the premise: “As an online discussion grows longer, the probability of a comparison involving Nazis or Hitler approaches one. In other words, Godwin observed that, given enough time, in any online discussion—regardless of topic or scope—someone inevitably makes a comparison to Hitler and the Nazis.”
I suspect there is a TEFL equivalent in that all discussions amoung teachers invariably end up criticising a specific coursebook, at which point the conversation is better left die a death. Your comments welcome and the first person to mention Nazies or coursebook will be … embedded and forgotten on page 120 of the nearest teacher’s book.
