Elsevier buys Mendeley!

It was confirmed today that Elsevier has bought Mendeley for a sum of money somewhere between $69 and $100 million. Mendeley is a platform for academics and organisations to share research and collaborate with each other via a social network.  It has been in operation since 2008.
Given that all the Mendeley staff are moving over to Elsevier this may signal their intention to become more involved in the world of open and social educational data!
