Breaks are good. They add to the sense of the plot, the development of the main characters and the structure of the piece.
When I see a poem, I lose interest if it is one seamless swatch of words. I enjoy the cut-up effect of stanzas. It is the same with stories. Sometimes the gaps are a clean scissor-chop, ready for a flash-back or a progression or a change of scene/mood. Other times, they feel ragged, bringing in sudden storms and violent twists in the action.
When I check the appearance of a story or poem, I find that playing with paragraphs and stanzas can improve, even clarify, the piece.
