Yammer is also announcing several new partners that are integrating their products with Yammer's software, including Hootsuite, the social media dashboard application that lets people manage multiple accounts from a central interface.
Now, users will be able to view their Yammer notifications in Hootsuite, and also post and search for Yammer content from the Hootsuite interface.
Other new integration partners include MindFlash, Get Satisfaction and Mindjet. Yammer now has about 30 such partners.
"Yammer appears to be picking up the momentum for its partner application network, which customers will also appreciate. We expect 2013 to be the Year of The App Store for enterprise social networking providers," said Jim Lundy, an analyst at Aragon Research, via email.
