Users can also follow tags to stay updated about new content relating to a specific topic across communities.
Tag clouds (such as the Trending topic in the startpage, or the Tags widget in the community overview) allow users to hover over them and see a button where they can follow or unfollow tags.
When a user follows or unfollows a tag, the startpage tool bar is immediately refreshed accordingly.
Users can see the tags they are following and their recent related activity in the startpage newsfeed.
Users are able to unfollow a tag just by clicking on the “x” on the startpage tool bar.
