The big rumor flying around today is that Microsoft is looking to buy Yammer (www.yammer.com) for a hefty $1 billion dollars making it one of the largest acquisitions by Microsoft of late (the other being Skype).
For those who don't know, Yammer is a social messaging network built for enterprise. It may seem kind of niche but in this services area, Yammer is the top provider and we can see why Microsoft would want to acquire the company.
For one, between Skype, Lync, Messenger and GroupMe, Microsoft is gobbling up a lot of social media services and building quite an messaging empire. Combined with their close relationship with Facebook and LinkedIn and you can see how Redmond is angling against Google for both consumers and enterprise.
The Yammer deal is expected to be completed today or tomorrow and if so, we could see Microsoft integrating Yammer directly into Windows Phone in the near future. After all, they already have Facebook, LinkedIn, Twitter and Messenger in Windows Phone 7.5 and they're expected to add Skype and numerous other social networks to Windows Phone 8 "Apollo".
What's more, Windows Phone 8 focuses heavily on enterprise including Bitlocker encryption, secure boot and new Office 365 policies. Yammer and Windows Phone 8 seem like a perfect match, if you ask us.
You can pick up the official Yammer app in the Windows Phone Marketplace in the meantime.
