Perhaps that's a lingering snobbery regarding self publishing authors (which is foolish, idiotic and wrong -
headed in an
age when some of the biggest
writers are rapidly moving towards self publishing, are already self publishing or have emerged from the self publishing space).
Technology has enabled
writers, typists and scribblers to add «stuff» (nod of the
head or attribution to George Carlin but also to the geniuses of all
ages) to the universe unknown to human beings in preceding generations.
