Newsfeeds in SharePoint 2013 provide a way to track people, documents, sites, and interests (tags). Newsfeeds are accessed and managed through your user profile.
The following walk-through will explore creating and managing newsfeeds.
These same steps are performed as part of the exercise with this lesson, so, unless you have a separate account you want to perform the walk-through steps on, you should wait to perform them in the exercise.
There is also a Newsfeed link in the Quick Launch of your user profile page. The link on your profile's Quick Launch navigates to the same location at the link in the upper-right corner of the browser.
