Twitter

Twitter discussions are quicker and easier to have than a blackboard discussion. The app itself is just more accessible and easier to use on any device. Often people use their twitter account more often than their blackboard account anyway. However, an in class discussion would probably be the most efficient and intimate way to have a discussion if all of the students in the class are comfortable speaking with one another. Sometimes you find that people are more comfortable voicing their opinion about certain topics through a computer screen rather than face to face.
