I think that this is a very debatable topic. I think that there are many things to support it and there are many things against it.
Some examples for it is that Facebook is such a huge and powerful tool. You can do many things with Facebook. You can talk to your friends and talk to people all over the world with it. If you didn't have Facebook you wouldn't have the ability to talk to your family and friends. An example is i have a 19 year old Uncle who lives in Fiji. We've never met or talked face to face, but with Facebook i'm able to keep up to date with him and I'm able to find out how he's doing. We go on Skype and talk about what he's doing with his life. I got to have a conversation with him that I probably would never have had if it wasn't for Facebook.
Social media also brings people together. Twitter and Facebook allows us to find out breaking news in a matter of minutes. Back in 2010 when the earthquake hit Haiti it was all over the news and social media sites. And everyone knew the devastation of Haiti after the earthquake. There was a lot of campaigns out there asking people to donate money to support Haiti. With Facebook and Twitter people came together and millions of dollars was doninated. Another example is many huge amazing artists came together and recorded the songs "We Are The World". After that song was released to the public, people saw there favourite artists taking part and it motivated them to help out and take part as well.
A negative is that people's social and communcation skills are suffering. I find that now a days that you don't see a lot of people talking face to face anymore. They just talk to people through Facebook, Twitter, e-mails and texting. People find it easier to talk through different social media sites because it's quick, fast and easier. But people don't relieze there communcation skills are suffering and they pick up a lot of bad habits and say a lot of bad things that can get them in a lot of trouble.
In conclusion i think that this topic is split down the middle. There are many things for it and against it. My blog argues the positives and the negatives of social media bringing real social change.
