Apology accepted. The tone in the first part of your original comment was condescending and you needed to be told so. Maybe you thought your statement hinted at "how ideas can be traced back to common beginnings", but you did come across as a boo-parader. There was nothing blooming about that. And no, I never think it is pointless telling people they are rude. Otherwise, rude people think their behaviour is accepted. The rest of your original comment was constructive and I enjoyed that. I refer to Anki in the preso and I hope it doesn't seem like I am trying to claim that I invented spaced repetition.
