Twitter Increases Student Engagement--Could Sticky Notes Work?

A study is coming out shortly in the Journal of Computer Assisted Learning. Mashable has a summary of the findings. 

"Communicating in 140-character segments may seem to contradict the goals of generally long-winded academia, but a new study has found that the two are less opposed than one might think. Students in the study who were asked to contribute to class discussions and complete assignments using Twitter increased their engagement over a semester more than twice as much as a control group"

Back in the 1990's I did a paper based in-person simulation of the online learning environment. We used newsprint to represent discussion boards and sticky notes for messages and emails. Now I a wondering if newsprint representing the classroom stream could be used as a low tech way of providing a twitter like messaging service. We use sticky notes a lot for ideas and questions that come up during a presentation but don't feature them like a twitter stream. My daughter gave me a pack of sticky notes that had Paper Tweet printed on it and spaces marked for 140 characters.
