Yammer Adds Groups Functionality

Los Angeles-based Yammer, the corporate focused instant messaging service spun out of Geni.com, said today that the firm is updating its service and adding a new groups feature. According to Yammer, its new Groups feature allows messages and members on the site to be managed around specific groups within companies. The new feature allows companies using the firm's service to subdivide members into specific groups, rather than to an entire company. Yammer launched to much fanfare in September at TechCrunch50, taking the instant messaging features of Twitter and adding a corporate spin. Yammer said the new Groups feature and related changes will go live on Wednesday. The firm is headed by former PayPal executive David Sacks, who is also CEO of Geni.com.
