Twitter - Straw Poll

A few of my classmates just did a presentation on Twitter. In all honesty, I didn't really get the point of Twitter at first, I didn't see much application for it in the classroom and it actually seemed a little egotistical for me. However after the presentation I am opening up to the idea...a little. I went out and searched for some applications that could be used in the classroom and to my surprise there were quite a few. I found one in particular that I like and it is call Straw Poll. This is where someone can create and answer polls on Twitter. I thought this would be a great way to start a unit about graphing and collecting data. Students could post a poll on Twitter about either a specified topic or one of their choosing and then analyze their data and present it to the class. Overall, I am not entirely sold on the concept of Twitter in the classroom but I do see some possible benefits and applications. But do the benefits outweigh the possible negatives? I'm not sure...
