Internet, know what to post and what not to post.

When talking about personal issues, you not find people who truly understand the nature of the Internet, expressing confidential or other private information. I believe that a person who is educated from a Liberal Arts University, leaves that University more broadly rounded and prepared for the ways of the World. This has nothing to do with those attending Universities for the purpose of attaining or achieving more specialized Educational endeavors. I hope that people will wake up and realize the Internet is not innocence in this conversation. The Internet is an open platform, I remember sitting in Science Lab behind those microscopes and staring down at those little Petri dishes getting ready to examine some microscopic organism. To this reminds me of all those who never give thought, at exactly what the Internet, can be, you see,  you are what's being examined that on that petri dish, in front of the entire world. Whatever you are engaged in on that Petri dish is Being looked through a magnifying glass.
I'm just amazed.why would people do that?
