This is very interesting. I came across the VR mapping last month at an event (it was introduced by one of your JISC colleagues in Wales) and was inspired to draw up my own (see https://libalyson.wordpress.com/2015/07/27/developing-digital-literacies/). I have two different ‘professional’ jobs, as well as a personal life, but I have quite separate profiles around these areas ie two work blogs, one work FB and one personal FB. But, I think this reflects on me, as a person, rather than the merits or otherwise of converging or being separate. Like you I remain ‘professional’ in all that I do, and although I am the same person whether it’s my f/t work, or my p/t work, or in my personal life, I currently like to keep them separate. The danger is that I don’t look like a very rounded/normal (!) person in the ‘work’ profiles, but I know I simply could not use social media for one of my jobs if it strayed away from work in any way.
