Wishes on the Wall

Wallwisher is useful in a sense that you can as a class or group of people can brainstorm and share all their ideas on their wall. However, one of Wallwisher's limitations is that you can only post up to 160 characters on each sticky which can be quite inconvenient at times when you want to write something long and you would have to link multiple stickies together. This i find is a good way to improve our summarizing skills. I think Wallwisher can be used as a place to share ideas in a learning activity like in a classroom lesson.Thank you!
