The Internet makes no distinction between personal and official

Most of those present here work in any companies. Someone may lead corporate blogs (as a trustee or manager), and someone is the “press attache” of his company. I have a question, do you separate work in your company from your personal life? What I mean. At work, you are an official, but when you come home, you keep your personal diary on one of the most popular services, you do not always communicate on forums on professional topics, post pictures with your wife or friends, and the Internet is a field in which there are no boundaries. Apparently, it is necessary to share personal position and official, personal life and life as an employee of the company. This can be done by setting up a separate nickname for the workers needs, a profile on all the necessary blogs and forums. And you can not do this. This is the question - what position do you hold, what would you do in this case, or would you act if there was a need?
