Getting use to using tweeter. But I see how it can be a useful, especially for professionals or even students. For example, if you were working on a project in a group, posting the status, questions and answers to items that pop up would be very valuable. Also, for people who work together but do not see each other, have varying schedules, don't have time to make phone calls, etc. Tweeter would allow such people to keep up to date and communicate quickly and easily.
