What Does Facebook Wall Mean?
A Facebook wall is part of a Facebook user's profile where the user can post status updates and receive messages from friends. The wall is a public portion of a user's profile in that the user's friends are able to see it. The wall also shows updates of a user's recent activity such as comments the user has posted on other friends' walls, the user's status updates and who the user has recently friended.
The Facebook wall is an interactive feature. Friends can respond to wall posts publicly (wall-to-wall), or privately through a private message. All the message recipient's friends can also comment on the wall post.
