Everybody has at least one social network, but the real thing is do we all use it in a good way?
This is an interesting topic on this days because not every person use them wisely, some use them to bully other people in an anonymous way or to do some crimes like raping innocent people.
This networks are one of the most useful things we can have but we need to learn how to use them, maybe we could talk to a friend that lives far away from your city, or even if you want to sell something they can be really useful also if you are searching for a new job and one very important, you can find out quickly about the news.
If you have a social network you need to know how to use it, and manage your time on it, because nowadays every person, no matter the age spends every minute on Facebook, Twitter etc. and the real communication is getting lost.
