Social networking sites

Social networking sites are not new. I have been investigating a little and I find out that they were first introduced to the world in the late 90s, but they don't became very popular until the new century because at first, not everybody used to have a computer at home and were thought to be too "advanced". Nowdays, for many people, mostly, the teenagers, visiting the social networks sites like Facebook, Twitter or MySpace are part of their daily routine. Sure it's a good way to keep in contact with your friends or family but in my opinion, this sites can be only beneficial if you know to use them in a certain way because these can also be detrimental if you use them in the worng way.

Firts of all, these sites make it possible to interact with people next door or even, across the world very fast and with a simple gesture: one click  This allows you to keep in touch with the people who lives far away from you whoever and whenever you wanted to. 

Second of all, one of the countless features that many of these sites have, is that allows you to upload or dowload pictures. This is very helpful for sharing pictures with friends and family, but there is one thing more that could be a good or a bad thing: the capacity of people to comment on your pictures. It's nice to see what people thinks about your pictures, but often times, some people don't have positives things to say.
Another drawback about the networking sites, is that some poeple act completly different over the internet than they would act in real life, or sometimes, people can trick you (there is a TV porgramme called CatFish that it's about these tricks through the internet). 

Finally, the most common disadvantage of social networking sites, is the addition. Often, users of these sites get addicted to it: they spend hours using these sites and it can cause mental health problems.
