Beside these disadvantages, Facebook has lots of advantages. We can keep in contact with our relatives
or friends who lives far far away, we can know what happens in our surroundings, we can chat with our
friends.What is more we can make secret groups where we can invite who we want, and then we can
chat privatly and the groups has own message wall. We are able to post everything from everywhere.
We can post to our friends message wall and anybody can see it. The largest advantage of this social
network is that millions of people are registered from all over the world so you can find all of your
friends, and the other one is that you can get feedback by "like" and "dislike" buttons.
All in all if you use smart the Facebook and other Social Networks it is really usefull, but if you do not,it can cause huge problems.
