Twitter

I can see how Twitter is a quick and effective way to communicate to a large group of people. It makes me feel connected to people I have never met, or friends that I have grown apart from. On a professional level, a teacher could set up an account and have his/her students become followers. She could post homework assignments, readings, or articles that the students could be interested in. It would make the classroom more interactive. It could be problematic, though, if the teacher used Twitter to post assignments without announcing them in class. If a student didn't check online or didn't have online access, there could be issues when the class rejoins the following day.
On a personal level, I'm not a very big fan of Twitter...yet. I like it when people post interesting news or articles, but I think all of the personal tweets can be a little bit too much for me. I think my Twitter use will be on a more professional level.
