Yammer has released the largest update to its service since Microsoft acquired it for $1.2 billion. Users can now see updates and comments from colleagues on the home page, which can be adorned with company logos and designs.

There are now file-sharing features, Trending Files and Company Resources, allowing users to see the most viewed and newest files and story important or frequently requested files. The site is also adding @ mentions a la Twitter, conversation replies, group announcements and (taking cues from Google) Yammer’s inbox includes a priority inbox and a search box to find old messages.

Yammer is also adding new app integrations such as social media dashboard HootSuite, first among its business social networking competitors. It’s also added Bevalley, FuzeBox, Get Satisfaction, IFTTT, Kanjoya, Mindflash, Mindjet, and Zapier to its app library.
