Communication based on my ideas

Communication is essential in our lives. Nobody would reject this,  but... have we stopped to think what is the best way to communicate what we mean? As Walt Disney said "Of all of our inventions for mass communication, pictures still speak the most universally understood language", which means that a picture is worth a thousand words said. Me, as I am studying journalism and I think that is something that directly affects me, I’m going to say the best ways to communicate that we have, on my opinion.
We would not understand communication nowadays without technology; yeah, I know it's a recurring theme, but we are not allowed to understand the world, in this moment, without whatssap, twitter or facebook. Social network is winning the race to traditional media, but I have no doubt that there will be other media that, in the future, will remove the ones that we have today. And why are social networks so successful? Because they combine the ability to share ideas by text (this is comparable to the text in newspapers), with the ability to hear what others have to say (as do the radio) and people can also share videos, no matter if they are of their own or from another people (television, audiovisual media).
To conclude, I would say that communication is a constant in our lives, and what should prevail over all these media is the ability to express ourselves; because having expression freedom, is not the same as knowing how to use it.
