I'm not sure I understand the issue you're raising here. Currently, if you received lots of messages a day, you have to go hunt them down to respond. The notification system for Message Wall puts them all in one place, and it will automatically mark as read when you visit them, even if you don't go through the notification links (this part isn't working on the test version yet).

You won't have to manually check back on walls you've left messages on to see if something new is there -- you just have to click menu items.
