- your wall and some one else's wall are displayed side by side so you can see the conversation you may have had going
Specifics:
- you click on a link in another person's profile "Wall to Wall" and it brings up all posts you made on that person's wall and all the posts he/she made on your wall so you can see the course of convo
This will improve the following aspects of the site:
- the wall will be used more for socialization and less feedbacks.
- facebook does this too and its very convenient
