Remember when MySpace was the social network giant less than a decade ago, gulping up new users as it grew to include a huge following?

After some decisions by MySpace that may have caused it to fall behind technologically, amid concern from some consumers about personal privacy, along came Mark Zuckerberg who answered the need and came up with Facebook.  Offering a layer of privacy from strangers’ peering eyes, it became a hit with parents concerned about their children’s safety and then, amazingly, became a hit with the parents themselves.  Facebook was the new darling of social media and exploded as tens of millions signed up.
