I have now worked at four institutions. When I first moved from London to Bristol University it was a real wrench… I missed friends and had small kids. But the next move to Southampton was much easier and I realised it was because my network of friends and colleagues was virtual - not geographically defined. This feeling has expanded exponentially in recent years with my use of social media. I now feel truly globally connected and have many new friends/colleagues who I first met/got to know through Twitter/fb/blogging etc. Thanks in particular for Martin Weller for getting me into all this. I think the implications of this are potentially profound. It has changed the way in which I do and communicate research. I love the mix of banter and professional exchange, the shared sense of passion for our field. I use social media in a range of ways: to keep up with new things, to pass on good ideas and references to others, to post new ideas and research work, to disseminate the work of others, to exchange ideas and to ask and respond to key questions of the moment. I genuinely feel part of a global community - quite something… What are other peoples experiences, positive and negative?
