Social medias

What is a social media?
  A social media is a site where you can share and post things,info,photos,videos,etc. And also chat with your family or friends. There are different types of social medias or social networks such as forums,sites where you can post photos,videos,poems,sites or apps exclusively to chat.
  In my case,I have 4 (four) principal social networks: Facebook,Youtube,Deviantart,Tumblr and sometimes Twitter,and i share basic information like my name and surname,my birthday,my gender,my location (just my country,not province or city) and the things i like and dislike. On some of my social networks i just share memes or videos,in others i show my work like my drawings,animations or my homework like these blog.

The influence of social media on teenagers is of particular importance,not because this particular group of children is developmentally vulnerable,but also because they are among the heaviest users of social networking. While they are using a social network, teens have the opportunity to learn,share and post things or make friends but also are exposed to suffer different things like cyberbullying, depression, or sexting. Internet,and more important: social networks have good and bad things
And i reckon the most important advantages and disadvantages are these ones:

But there are more,i just believed that those were the principal ones:

Advantages:-Instant worldwide connection

-Many people have found a job through advertisements on many social network groups

-Thanks to social networks, many problems have been reported or many problems can now be recognized because of the massive people who share the publications 

-Expand your business and projects, if you have a business you can share the location,publish your ideas and find your customers' preferences. If you have a project you can find people interested in what you are doing so you can  become popular and success

-You can be yourself,on the internet you can be free and anonymous,in many social networks you can share the things you like without worrying about what the others think

Disadvantages: 

-You can get hacked.

-some people neglect their real social life,job,family etc,because they are addicted to social networks or internet in general.
-if you put too much personal information they can steal your personal identity
-if we use too much a social network we waste our time and productivity
-Sometimes, people who use social networks have a false self-esteem, they share their photos just because they want likes and if they don't get them they become depressed
-Some people publish and share all the things that they are doing all the time,that's not only very dangerous,but is also really annoying.
