On "Who are you quoting"

We know that every possible sequence of symbols appears in the digits of pi

therefore, any given sequence of symbols found juxtaposed to the blockquote marker '>' shall itself be found at a location L in the base 256 digital expansion of pi

Based on the above we may immediately refer any person asking "Who are you quoting" to pi itself.

But pi is only tau/2, thus anyone quoting pi is actually quoting tau.
