Dive Brief:

• A new feature has been spotted on Twitter for its desktop trend box — a section of the homepage that delivers 10 of the most popular topics on the platform. 
• Previously, the trend box would just display a keyword, but the social platform seems to be testing out explanations for each of the top 10. 
• The definitions aren't clickable, but rather appear to be texted pulled from headlines with tweets on the topic. 

Dive Insight: 

Twitter seems to be taking more responsibility as the leader in real time news. The testing of this feature follows another feature spotted last month -- the hashtag definition. The move will help marketers who depend on knowing the trending topics on Twitter, and not to mention, knowing what a trending topic or hashtag means can prevent some embarrassing mistakes by marketers who accidently jump in on the wrong topic.
