Yammer Just Became The Enterprise Facebook, Launches A Platform

At the Techcrunch Disrupt conference today in San Francisco Yammer announced the launch of a redesign (which is identical to Facebook) and a Platform which lets developers build applications on top of the product. It’s an impressive product in that it has literally become the enterprise Facebook. David Sacks, the founder of the company, also announced a Questions product which literally duplicates Facebook’s existing questions product.

What’s probably most significant about this product is that it has made the evolution from being a Twitter-like product to a Facebook copycat.
