Facebook will add new feedback buttons to stories in the news feed, according a TechCrunch source. Starting with “Read”, “Listened”, and “Watched” buttons, users will be able to indicate that they’ve already consumed a piece of content. This will allow them to provide more specific information about how they’re related to different types of content, which could help Facebook refine the news feed to show them more of similar types of content. The tip matches with the tagline “Read, Watch, Listen” which AllThingsD heard will be used for the f8 conference.

The granular feedback could also power the quietly launched Broad Category Interest targeting available in Facebook Ads, which lets advertisers target anyone with interests related to a selected subject rather than targeting those with specific Likes. For example, advertisers could target the category “Literature/Reading”, and Facebook could show their ads to users who frequently click the “Read” button on posts about news articles or books.
