Not to be overly pedantic but what would be a "general readership"?

For example, I understand that the patent dep't was an early Unix 
customer.  Would they been a general readership (and how were they taught)?

(I would think that many of today's grunt-and-poke UI generation would 
have difficulty with a cli.)
