Social Media Perception & Professional Learning

How can/should social media be used to help you develop / collaborate / communicate as a professional? What are the critical issues to consider?  
It shouldn't. There is a reason it is not titled professional media, educator media, or student media. It was never intended to be those things. Yes, I acknowledge that as a society we have an unnatural affinity, affliction even, towards social media, but that does not mean we should incorporate it into every facet of our lives. This is the issue many skeptics have with technology, i.e., incorporating it for the sake of incorporating it versus using it for its intended purpose - opposed to some self-created purpose. Social media was meant to communicate about social issues and it is here where the term "social" is more of a euphemism as it refers exclusively to the posting author. Am I being narrow in my definition of social media? Yes, but I am tired of nuancing thoughts to satisfy some questionable practice. So, here are my critical issues:

• why? with so many other pressing needs, what is the win win by incorporating social media into a media saturated student population
• nothing is sacred. there is a reason bullying, harassment, etc. are more problematic than ever - people put there inner most thoughts out for all to see and respond to. can't say this is super healthy. sometimes deep seeded inhibitions are best kept private
  
• growth mindset. if one stupid post has the potential to ruin your academic and professional career, we are setting people up for disaster. we are fallible
  
• it was not intended to teacher history, math, English, etc.
  
• it is generally one way communication, we are straying too far from authentic dialogue
  
• kids need to practice at life. when the world is your stage as you are working to figure things out, you are bound to falter...hard

What would you do if you were to come across an inappropriate post made by one of your students outside of the school. Do you address the post and, if so, how? Whom do you involve in the conversations? What considerations must you make in determining your course of action?   

• Happens all the time. I always notify both the student and parent. Legally I have no jurisdiction over what they do on the weekend, ergo I do not overstep my limited authority, nor do I pretend it is any of my business. That said, I do stress that "it" arrived on my plate, meaning it is assuredly on countless other people's plate. I always stress that they have lost control over where the image/information rests now that it is live.......and I need to call mommy and daddy so they can implement their alternate means of correction.
