Creates user groups and streamlines communication
I think we should have some improvements in Yammer, similar to what we have in Facebook and others, where we can have targeted communications, so that we can filter some communications to go to a specific subset of that group, not to everybody. We would love to have some AI technologies included in Yammer, but I do not have a specific use case in mind right now.
