The default feed on Yammer is the "All" feed, which includes messages posted by anyone in your network. As your network grows, you can use the "Following" feed to surface the information that is
most significant to you. This custom feed only includes messages
posted by the people you follow or that include the tags you follow. This filter enables you to determine which messages you want to receive, based on the content you feel is most relevant.
Following the people and tags that you find most interesting is the key to getting the most out of the following tab.
Following people
When you follow someone in your network, all of their messages will appear in your Following feed. For example, you can follow colleagues who work on the same projects as you, are involved in interesting initiatives in your organization, and who share insightful links. And of course, don’t forget to follow your boss!
Click on a colleague’s name or picture to reach their profile, then use the blue “Follow” button to the right of their name to follow them. You can also find and follow lots of colleagues quickly through the members directory, reached by clicking the “Members” tab.
Following tags
When you follow a tag, you will see every message that includes the tag in your Following feed. Follow tags related to projects you are working on, topics of interest, or just for fun. Tags can be used for topics as significant as #revenue and even as ordinary as a #coffee, to announce when fresh coffee is ready. To view the tags being used in your network visit the Tags page, reached by clicking the "Tags" tab.
Use the blue “Follow” button on tag pages to follow tags that you are interested in. When you follow a tag, you will see every message in your Following feed that includes that tag.
