Twitter is one of the social networking applications for the Internet - you have the ability to post status updates from mobile devices, etc. Before Facebook and Myspace had mobile applications, this was THE mobile social network. According to Wikipedia, it's still the third most common social networking application, ahead of sites like Friendster and HI5, and behind only Facebook and Myspace.
One of the issues I find in the classroom sometimes is poor etiquette. For example, there are times I am in the middle of teaching a lesson, and I see a student texting or doing something on their phone. It becomes distracting, and it is a little frustrating to deal with. As such, it causes me to lose focus, and therefore, affects the learning environment for the entire class.
I (and many professors) feel like it is rude when students do that ... and that the class isn't important to them. This is why this article was something I can relate to:
Basically, a player from the Milwaukee Bucks basketball team, Charlie Villanueva, updated his status on Twitter during halftime of a game. His coach, Scott Skiles, got pretty upset about it, and, much like some students may think, he didn't think it was a big deal. The coach, on the other hand, felt like it showed a lack of focus on the game by the forward.
On some level I can relate with Coach Skiles.
