Maybe an extra billboard to 'post' information to or rumors that could be spread at the inn? Or maybe a 'broadsheet' item that could be handed to the character of one's choosing?
I'm not quite sure what DOES trigger conversations and communication. It's not every conversation you have, so I'm assuming it's what the NPC determines as 'important' (as decided by the model). More of them wouldn't be the worst thing but it probably wouldn't help if Hayden was running across the street arms flailing claiming that someone bought two pretzels and a sweetroll everyday.
