That also seems to be the case in the US as well. However, colleagues of mine have been thinking about it from a business and healthcare perspective, almost as an extension of LinkedIn and the like. I know I have a space for it through my NYU Epsilen account at http://www.epsilen.com/jk904 .

Not a lot there yet, but it is still new and I find I need some good models to follow to see if it is worth the hoopla.
