Facebook’s Trending Topics don’t show headlines and brief explanations anymore. The company has added a more automated design that strips human-written descriptions from its list of popular topics after months of criticism over how the social network displayed news stories.

You might notice chances as thus; instead of describing the topic with a headline, the new automated format simply highlights the trend – a word, phrase, hashtag, without any trouble. Those interested in knowing what the hubbub is about can hover the cursor to pop up a small window with an associated story and source.
