The alpha version of Twitter has a version of the Discover section that is different from the current app. Trending can be viewed in detail or in list. In detail, a couple of sample tweets can be seen giving users an idea of what the excitement is all about, and why a particular topic is trending. And when composing a tweet, a pop up asks you if you are in a particular city.
There is talk that Twitter is becoming less aggressive with its plans to change its Android app. Pulling back from the swipeable menu is no doubt an example of this.
