Facebook’s video destination, Facebook Watch, is introducing a new feature called “Your Topics” that will allow you to tailor its feed to include more of the content you want to see. Currently, Facebook leverages its existing understanding of each viewer’s interests to personalize the Watch Feed. Topics, however, will allow users to more explicitly tell Facebook what sort of things they like by exploring and subscribing to various content categories.

The feature has been quietly rolling out to Facebook users in recent days, and now some portion of the user base already has the feature in their own Facebook app.
