On the
Facebook,
social networking site a wall is a
section in your profile where others can write messages to you or leave you
gifts, which are icon-like small images. The wall is a public writing space so
others who view your profile can see what has been written on your wall. Once
you have received a wall message, you can respond directly back to the friend
who left it using the "wall-to-wall" mode. There are variations of the wall
available to Facebook users by installing Facebook applications, like "Super
Wall". These types of applications will offer features and options not found in
the standard Facebook wall.
