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.

3-D or No 3-D

Virtual interaction has been increasing for quite sometime. Recently I read an article of an individual whose social life practically revolves around 3-D communication. Countless people utilize this kind of communication to avoid the disruptions or irritating situations one would face in person. An exmple of this kind of interaction is second life, which people can communicate with the use of an avatar, which is a 3-D character created by the user. This site itself has many uses, socially and business wise. The real question is, can this form of communication replace a person-person conversation or will it be a passing phase.
