This explains a lot

Repeated exposure to social networking sites has left users with an identity crisis.
.
Similar to a toddler saying: "Look at me, Mummy, I’ve done this".
.
Baroness Greenfield, professor of pharmacology at Oxford University, believes the growth of internet “friendships” - as well as greater use of computer games - could effectively rewire the brain.
.
The effect could lead to a reduced concentration span.
.
A need for instant gratification and the inability to make eye contact during conversations.
.
More than 750million people across the world now regularly use Facebook to share photographs and videos of their movements and thoughts.
.
Millions have also signed up to Twitter, the ‘micro-blogging’ service that lets members circulate short text and picture messages about their lives.
.
Baroness Greenfield, former director of research body the Royal Institution, said: What concerns me is the banality of so much that goes out on Twitter. 
..
Why should someone be interested in what someone else has had for breakfast?
.
It reminds me of a small child (saying): “Look at me Mummy, I’m doing this”, “Look at me Mummy I’m doing that”.
.
It’s almost as if they’re in some kind of identity crisis. 
.
In a sense it’s keeping the brain in a sort of time warp.
.
Literacy expert and author Sue Palmer said girls in particular believe they are a “commodity they must sell to other people” on Facebook
.
She said: “People used to have a portrait painted but now we can more or less design our own picture online.
.
It’s like being the star of your own reality TV show that you create and put out to the world.

.
More than this most communications are banal and trite 
.
If we want a snap shot of peoples lives then this is indeed a sad picture.
.
A picture of millions of people endlessly twitting the trivia that makes up their lives
.
A life focussed on little screens
.
Screens that remove us from the beauty of the world around us
.
Changing our relationships into two dimensional twits

.
Until the unexpected comes along that is
.
Then we are faced with a new reality where twitting is not an option.

Beware Black Swans!
