Long, rambling messages inspire feelings of pity and guilt. The longer the message, the more likely the recipient will feel obligated to send a polite response. Also, when a woman sends a polite negative response to a man, he's likely to respond with, "Thanks for responding, good luck in your search!" That shouldn't count as "starting a conversation," but according to this blog post it does.
