Well isn't this brilliant...
I don't know many people who aren't aware that 4 of the digits reveal information about your age and place of birth. That being said, it's not always accurate; as you noted, people in rural areas/home births were frequently not issued SSNs at all until the early '90s, and these individuals have a different numerical suffix. It is not uncommon for someone more than 20 years of age to have lived a good portion of their life without one.
This article is far too vague. If you're trying to say that 3rd party information leakage is a problem, say that and move on. Despite all the bullets, this article fails to make its point.
