That is not true at all. All the messages that were sent to you will appear on the message wall, and if they are a lot, there would be multiple pages listing them, from the newest to the oldest, much like the comments on a page.

What I can say about the message walls (not sure if I should classify this as pros or cons) is that the signature won't be needed, since the name of the user that posted the message will appear at the top of the message, along with the profile picture.

A few pros that I can find in message walls is that multiple users can participe in one discussion and that all the replies to a message appear in chronological order.
