New Features Overview from Yammer on Vimeo.

Yammer rolled out three new capabilities to support enhanced sharing and collaboration. Those are:

• Activity Stream Ticker … for automatically pointing to activity in other parts of Yammer that people are doing, such as editing pages, or uploading files. Ticker also integrates with other systems – such as Box.net – to notify re activity.
• Pages with Real-Time Co-Authoring … online documents that offer character-by-character real-time co-authoring with other people. Pages can be used for many applications – meeting notes, developing wikis, and drafting documents.
• Files … for creating a centralized location for sharing files and documents across people and teams. In a sidebar, related content is also shown to support surfacing of related materials.
