Is there a creator whose content you really enjoy? You can follow them by clicking the Follow button on their channel or under their content.
Every time a creator you've followed uploads, it will appear in the Following category. This appears at the top of your homepage and on the expanded sidebar.
Videos under Following will show in the order they were published, by default.
