An interesting look at some reasons writers choose to publish their work and why some writers choose not to publish their work:
Alone, With Words | The New Republic:
Writers who publish with small circulation magazines and tiny, non-commercial presses can sometimes achieve an astonishingly powerful presence, because they’ve acquired their readers gradually, incrementally, one by one. And the writer who begins with the big blastoff by the major New York publishing house can all too easily vanish. Nothing is for sure. The writer who holds back too much may well be a hopeless neurotic. But if there are risks involved in resisting the public, there are also dangers involved in running after the public. Nobody talks about those dangers anymore.
