2. Facebook
I usually use facebook as a way to find some page or group that I
can feel entertained and as a way of communication between friends
who are distant. The mechanics of using the site is easy and anyone
can use it.
3. Snapchat
My use of snapchat is recent, in the country where I am, we do not
normally use this app, but in the USA, practically everyone uses it
as a quick form of interaction. The use of this application is much
more for personal conversations, but groups can also be created.
4. Instagram
Instagram is an application that publish photos, your "story" of how
was your day and also private conversations. This is what I use most
because it is more complete in my opinion, in it I can see from the
pictures as my friends are, where they went and obviously they can
see about me too.
