Yammer is a Twitter based internal corporate communications tool for businesses. They provide a great model for companies to use Twitter inside their company in a closed and private way where employees can sign up and communicate with their co-workers across the company’s network. This is an excellent idea and looks to unite people across different departments without having to pick up a phone or physically walk to them.

The catch to their monetization process is this, if the company itself wants full control of the chatter and its employees, that’s when the model turns profitable and businesses pay into the service. TechCrunch’s article states “There is such a huge demand for this type of service that 10,000 people and 2,000 organizations signed up for the service the first day it launched on Monday.”

Pretty amazing numbers that only look to go up in the coming months as internal corporate communication tools will be a necessity for day to day operations. If you’re in a business looking to building community amongst your employees, definitely check out Yammer.
