Wishes on the Wall

Some useful features of the Wallwisher are that we can post our thoughts immediately on the wall and thus, allowing other people to view our thoughts instantly. While we can do that, theres a limitation to the amount of words that we can write in a post and so, if we want to write more than the amount of words that they allow us to, we would have to create another post. I think that Wallwisher can be a useful learning tool in learning activities such as when our teachers wants us to post our replies to her question, we can post on wallwisher and she/he can see it instantly
