It appears that Microsoft wants more than just a slice of the social networking pie. If you thought theirSo.cl project was the only social interest the company had, think again. Microsoft has purchased Yammer, an Internet startup company, for $1.2 billion. This is all an effort to bring more social networking features to not just So.cl, but to all of their business software. This is very similar to what we are seeing in the collaboration efforts with their Windows Live suite, Office 365 and the OneNote IE9 integrations.
What is Yammer and why did Microsoft want any part of the company, let alone the whole thing? Yammer's freemium business model focuses on private social networking. Employees of the same company can connect with each other and see what each of their coworkers have going on in their business lives. Essentially, it's Facebook for work. Microsoft's new acqusition will allow its sometimes fragmented business suite to finally be pulled together in some way.
