Many are bewildered by the explosion of social media. And, unfortunately, it's not unusual that humans denounce what they don't understand. Let them eat Tweets in today's NY Times is a recent example. "Twitter is a trap...connectivity is poverty..."
As a Business Anthropologist, I take the liberty to ask that everyone take a deep breath. Yes, our world is changing greatly, and rapidly. But not everything is changing. Humans have always gotten by through exchanging with each other, whether cooperating to keep young away from predators, trading precious material, or -yes - sharing stories and perceptions.
I take exception to the suggestion that "connectivity is poverty." On the contrary, connectivity is how people thrive. If you think rich people don't care about their cellphones, try taking them away.
Social media are powering a revolution. They will play a big part as the economy continues to morph and reinvent. I invite those who do not comprehend the value of Twitter to go back to their high school economics texts. There you'll find that money is not THE measure of value; it is A measure of value. And fairly recent in human history.
Exchanging is as old as the first human community, perhaps 300,000n generations ago. Money has been around for roughly 40 generations. I'm not a bit surprised at the current explosion of exchanges that don't involve money.
They're certainly not an indicator of poverty. Rather, they point to changing seats of power. Away from the bean counters. Eureka.
