This raised more than just a few eyebrows, Microsoft announced last evening that they would be acquiring Yammer for 1.2 billion Dollars. Yammer has nothing to do with Usain Bolt and his ability to smoke the opposition over 100 metres, but rather a plug in piece of software that was supposed to improve productivity. That probably really does that. What is Yammer? Well, we used it once here and then promptly uninstalled it, for the only reason that Yammer is actually for bigger organisations with multiple users. It is basically a closed network of users who can interact with each other on chat, replacing memos, but has file sharing abilities as well. So, if I remember right, the software runs on your desktop, and integrates your calendar, tasks and all those clever things that Microsoft has achieved in their software over the years. But, 1.2 billion Dollars? I worked it out, it is a mere 14 and a bit days of Microsoft's EBITDA. Two weeks. That is it. And, if you forgot, Microsoft has a war chest of around 60 billion Dollars, in the bigger picture this is not a giant leap. So, expect the next patch in your new Windows operating system soon.
