If you are having issues convincing anyone about the role that Social Media will play in the future workplace, I highly recommend that you point them to this 13 minute video “Social Media @ Work”. A compelling insight into how Social Media is already driving change within many workplaces.
The standout quote for me is at approximately the 12 minute work where the interviewee says “by 2013 we will not have email in this organisation anymore, we will be doing everything on Social Networks”
