Crack cocaine is so pleasurable for its users that compared with it nothing else matters so much - it is highly addictive, dependence producing, and withdrawal leads to misery and drug-seeking. Many or most humans are pretty much helpless in the face of experiencing crack cocaine - the drug is stronger than human agency.
The combination of 'social networking services' (Facebook, Tumblr, Twitter, Instagram, Pinterest, YouTube etc) with ubiquitous mobile smartphone technology seems to have an analogous effect on young women: compared with messaging nothing else matters, they are pretty much helpless - the drug is stronger than their agency.
That this is a fact is obvious - just look around you.
Whether sitting, standing or walking; in private and in public, alone or with friends and family around them; at work or in leisure; eating or at the toilet; in any time or place possible, young women are social networking in preference to anything else.
Nothing else matters so much.
There has never been anything like this in the history of the world!
Does it matter? Is it just a bit of a laugh - nothing to worry about?
Well, does it matter how people spend nearly all of their time; or not?
You tell me.
