Twitter’s Trending Topics can be confusing. You might have no idea that #NYFW means New York Fashion Week. So today it’s replacing the Discover tab with an enhanced Trends section
that includes brief descriptions of what each trending topic is about.
For now it’s available to U.S. users in English who have Tailored Trends
turned on, but Twitter is experimenting on the web and plans to roll it
out to more countries.
These explanations are similar to the descriptions Facebook included when it launched its version of Twitter’s Trending Topics
in January 2014. By giving people context, Twitter could make its
product more accessible to the masses, aiding growth, and get more
people participating in trends.For example, you might see Phantom 3 and have no idea what the topic is about. But now Twitter will tell you that “The World’s Largest Drone Company Unveils Newest Product DJI Phantom 3″.
Previously, Discover was its own tab in the Twitter bottom navigation bar. Now that tab has been eliminated, and the new Trends with descriptions will appear when you tap the search icon atop the screen. Tapping into one of the trends will show you top tweets about the topic, media, tweets by people you follow, and then a wider breadth of posts mentioning the topic.

Replacing Discover with the enhanced Trends will give users a better way to see the most important things happening on Twitter, which was probably the intention of Discover all along.
