Social media, connecting us all via the internet. It is something that is making the world more accessible and in a sense smaller as we all tend to know even the most minor of details from someone's life or the news that is being transmitted from the farthest reaches of the earth. Obviously, the big facilitors and most popular applications being facebook and twitter. But in other parts of the world they use social media sites like orkut to reach the same ends. Using these in classroom can be beneficial because it allows people to exchange information quickly and with great brevity. It is a novel way in which to communicate and can be accessed at all hours of the day, therefore the convenience factor is extremely high.
It would seem doubtful that social media will lose its influence and force in the near future, and as such it should be embraced and utlitized for its assets while it is present and in vogue. I am sure someone will eventually manufacture something that will usurp facebook or twitter a few years down the road, but as of right now I cannot think of it and am not going to be that millionaire, so I will teach.
