NBA prohibits twitter use?

After reading an article online about updates in the news, I came across one which I found particularly interesting. It was titled "New NBA rule prohibits Twitter use", my first thought was this new rule was relatively dumb, I mean what NBA player is going to pull out their cell phone in the middle of a game to tweet about their latest updates? The rule entails that players' communication devices are banned starting 45minutes before tip off and they may resume use after they have finished their responsibilities, this includes half time. What was even more ridiculous is that the memo sent out by the NBA also mentions that coaches and other team basketball operations personnel are included. I may be confused but I have never heard about or seen an incident where a coach whips out his cell phone, pulls up his twitter application, and tweets about his life. A few weeks ago when I was getting the syllabi for all of my classes for the semester, there was a section in every single one of them regarding the prohibited use of communication devices in class. This seems reasonable for a college class, but the NBA? This just goes to show how advances in new media have become such a distraction in our lives. These players earn so much money doing what they do, you would think that no one would need to tell them to turn off their cell phones for the duration of a game. But, I suppose that the fascination of twitter is just too much for these grown men to resist!
