First, I dislike the term "hacks" .. it's a disparaging term. Broadside poets is a better description I feel,

You are right, Derek, it is a denigrating word, but if we are not to use the word 'hack' then we need another to distinguish broadside writers of the past and newspaper reporters of today from 'songwriters', 'poets' and 'writers'. If not 'hack' then we need some word to call those who are forced to write to a very short deadline and do not have time for reflection or time to live with and refine what they have written.
The hangman was not going to wait for the broadside writer to come up with some beautiful prose or poetry written on reflection and as a result of research. The printer needed them ready to sell to the crowd where the execution was taking place.
