Fascinating, captain. Canna imagine why.

Now you're into psychology. (Not necessarily a cryptodigression:
consider how the business model for an Eternity system is
critical for handling various attacks/spammages)

Primates are easy to manipulate sometimes.
What docs *do* you retain? Controversial ones you think
might be pulled, sure. Aesthetic ones (incl. erotica)
if you think you might look at it again. (This might
include personal, objectively boring pictures.) Informative
ones, if you think you might refer to them again.
Look at the subjective-merits that factor in. Expectation
of future value; subjective current value. Ick.
You'd best have a varied selection of content (e.g., images
by all genres of artists; music by all genres; etc.) rather
than shoot for a single "hit" bitstring. All the content
would be stego'd, but diff't people download diff't
covertext.
How long do you need people to retain the content, btw?
Perhaps once you revealed the secret message "if you play
it backwards" the Saturation will increase.
