I must admit that I still don't see the natural fit between Microsoft and LinkedIn. Like Ars I've thought about it and I'm baffled. It gets worse when you mention the price tag and the 50% premium on the share price.
One thing I am certain about is I don't like agreeing with the Economist. So let's hope I am wrong and just not visionary enough as if this goes wrong fast its definitely going to cost Nadella his job.
