You can encode information in the relative timestamps of posts. The amount of covert data in social media (inc Q drops) could be enormous. Communicating in plain sight is a niche art, but a fun one! (And that's just one of the more trivial schemes...)

I wish we had the secret timestamp decoder ring. As things stand, timestamps are more entertaining for us, than useful. “LAYERS upon LAYERS” is an understatement.

I bet it’s “repeating recursive layers at different scopes with a monoidal algebra of concatenation and two degrees of freedom”.

But what would I know…
