Social media has become a tool which can be useful and can have side affects. If we post something on Facebook/Twitter, other people can see it. If they post something, we can see what they write.
Is this a good thing? What are the problems with doing it?
I follow my boss on Twitter and use Twitter to give some idea of where we are, what we are doing. I'm not friends with my boss on Facebook - not that I use Facebook much these days.
