Learning to "Tweet"

After using Twitter for about a week and a half, I am torn on the usefulness of the social media site. I had fun using Twitter and "tweeting" updates on my life and interesting news. While I enjoyed updating the world on my activities, I'm not sure those updates were at all useful to anyone. I can see the possibility for Twitter to be very useful in spreading news and for public relations, but some people hinder this possibility by abusing their "tweeting" abilities. Some people update many, many times each day with information that is not all that interesting. I think they are creating a "tweeter who cried wolf" syndrome. When they have something important to say, no one may be listening.
That said, I like Twitter overall and do find some great links in others' posts. I don't plan on updating very often, but I will maintain my account and read up on the posts of those I follow. I think this will be valuable because, as a communications student, I need to understand social media and how to use it properly. I also will learn about new social media sites, other sites and news.
