Whiteboards: "more to read" indication
Room-integrated message isn't all there is to see.

A room with a whiteboard in it shows about 200 characters of what's written on the whiteboard. A whiteboard can hold A LOT more text than this but it's very often not at all obvious that there's more to see than what you see in the room description.

@idea: Give an indication that there's more to read so that people will think to look at the whiteboard.
