A friend of mine is doing his Masters research into why most companies ultimately never last due to social networking inhibitors (or something like that). I highly recommend that you follow his blog and keep up with it as he unveils more and more research and also contribute where possible. He is looking for people to comment and provide ideas and concepts, similar to what has been done with guys like John Battelle & Chris Anderson, when they wrote their books.
He is clearly one of the most intelligent people I’ve ever met, and a Co-Founder of incuBeta (who subsequently exited to further his studies with this Masters Thesis).

His blog is located here.
