I have been running a LinkedIn group called Elon Musk Fan club - ( http://www.linkedin.com/groups?home=&gid=4481086 ) for over a year now. I started it just for fun as I wanted to promote Elon musk's strategies of sustainable economies. Also wanted to discuss his strategies and the way he gets things done so that we can learn and apply them in our businesses.
We have received an awesome response and we have around 3K highly active users. Please join in.
