Many people will say that #morseCode is "better" than #tapCode.
Insomuch as Morse is faster to transmit and receive once properly learned, this is true.
However, Tap Code is faster to teach and learn.
Tap requires learning a few simple rules to become good enough to transmit and receive messages. Morse takes years of rote memorization and strict practice.
#tapCode (#knockCode) can be disguised as art, doodles, noise...
Here, we see a nice, aesthetically pleasing design which spells out "Trump is in the Epstein Files."
Huh, look at that, you can encode #tapCode as ascii blocks
