Twitter or not to Twitter

I recently read a article discussing whether Twitter is fad or a productive way of sharing information. Honestly, at first i considered Twitter to be another myspace or facebook....but have come to realize it can be useful more than the others in a social network. As a student, I have to decide which classes to take and professor to consider. I have come across many classmates who found out intimate knowledge of how a class is conducted or by whom, by word of mouth I reconsider a certain class. One shouldn't misunderstand, Twitter is still used for telling a number of users what a person is doing at any particular time. So it is important to realize a person can find people to follow and tweet with similar interests r goals.
