Let´s see the real definition of what Social Media is:
There are lots of ways to "define" what Social Media is, but is good to REALLY know what is, in spite of the working knowledge you might have.Social Media is all about sharing, news, video, audio, pictures with people in your network. Typically we share with people we know and who are into our list, and network. There is always the chance to be people who are interested in you and want to know more about you.
By doing this, you become each day more discoverable. Mainly because your friends or people you are connected with re share your content.
Each time they LIKE, give a +1 or put your content to their timeline, this content exposed to new people.
Think it of like a party into a friends house... You go there in order to socialize with people. People with whom you got common interests. You do not want to be like the one who is standing on the corner, and shouts all over, just to make sure, he gets the attention. By making LOT of noise you turn people OFF.
This is the easy way, and most forgetable one, as when you really open your mouth to speak, you need to be genuine, and what you say must have a meaning.
There is always people who are shy, or prefer to be only active social listeners. Still those people once in a while need to participate and discuss, share an opinion.
Social networking is a perfect way to keep in touch with colleagues and friends, and to make new friends, perhaps create great recommendations and finally come out as a great professional with originality through your contents.
