Your Twitter app just got a shakeup, as the company has decided to retire the #discover and Activity tabs on both its iOS and Android apps. According to Twitter, the reasoning is that it's been working to put more content in the main timeline, which is most certainly true.
That means trends have to go somewhere, since they previously resided on the #discover page. Now, you can access trending topics by tapping the search icon.
Twitter is also providing more context to trends, since there's a good chance you'll often have no idea what people are talking about. #OneDZayn? Huh?
"We know that trends aren’t always self-explanatory, so now you’ll see a description below each trend. Since trends tend to be abbreviations without context, like #NYFW, a description will make it clear that this trend is about New York Fashion Week. The new trends experience may also include how many Tweets have been sent and whether a topic is trending up or down."
This is currently only happening for US users with taoilered trends enabled on iOS and Android. Twitter says its "experimenting with similar features" on the web and also plans on pushing this internationally soon.
