What's in a metaphor?

A regular has popped in with a comment on our prior post. Referring to Heidi Moore's osmotic twitter utopia, he or she notes that osmosis has the added benefit to a journalist or blogger of not requiring any input of energy. To which we add:

1). That osmosis takes a place across a semi-permeable membrane - one which only permits the entry of small, simple and commonplace molecules from the solvent side into the realm of the larger, more complex, and perforce rarer, constructions on the solute side.

and

2). The end result of unconstrained osmosis is that the complex fluids on the solute side become virtually indistinguishable from the primordial, lowest common denominator stuff emanating, for example, from Twitter.

A heartfelt thanks to Candide. But does Heidi know that she nailed it?
