Out of curiosity do you get confused when people talk about 360 degrees, or 90 degree angles, or turning around 180 degrees, etc?  Most people I know intuitively understand degrees and could easily understand radians the same.<p>Why should BetterExplained use tau?  Tau is a fairly niche idea that will only confuse way more than explain. That&#x27;s a bit like saying BetterExplained should be written in Esperanto.<p>Personally while I agree that historically pi would have been better off if defined as 6.28... instead of 3.14... (And even told my students this long before tau manifesto came out) I don&#x27;t feel that a factor of 2 warrants using up a whole other Greek letter.<p>(I&#x27;d be much more supportive of &quot;tau&quot; if instead of the Greek letter Tau Hartl chose a unique new symbol, much like physics uses hbar instead of h as he Planck Constant for radians instead of cycles).
