Their argument about the normal distribution is completely off though. There is completely no reason to group the two with the standard deviation. Their biggest argument seems to be that the area of unit circle is exactly pi. Sadly, there is absolutely no need to work with fractions of areas of the unit circle, while if you're working with angles the unit circle is a most natural standardisation. The normal distribution has been a lot clearer to me since I've understood the two should be grouped with the pi.

Their argument about trigonometric functions is completely wrong and obviously so. Trigonometric functions work with angles and it's already shown (and pimanifesto readily admits) that tau shines there.

Their argument about Euler's identity is as inane as the tauists' is.

They don't understand quadratic forms.

I'm guessing this site is sarcastic.
