It's this that is responsible for what is called the 'entrophy' that exists in communication the same as in the physical world. - Entropy is indeed a term used in thermodynamics as well as information theory. I want to insist on the spelling because there are also plenty of words on ..trophy (from greek "to nourish"), which have nothing to do with ..tropy, which is based on a root for "turning, changing".
Entropy of an information stream relates not to "unnecessary slime", but on the contrary to the information density (if the stream is intellegible).
