I've read a lot of blog posts recently describing the 4P's of Social Media that is, Public, Private, Personal and Political. One of the issues I have is the blurry divide between what you do on Social Media sites that is personal and what is professional and more importantly how you manage these two aspects of your life.
A few people I know have multiple accounts for sites like Twitter and Facebook and use one for their private life and one for their professional life. I would find this very hard to manage, but can see why people would want to seperate these elements of their life. Several of my other friends simply don't use Twitter professionally, they only use it as somewhere to write about their personal life, this is fine but what happens when you want to post something professional? Do you not post it, or do you use other mediums?
