Facebook is shuttering the much-maligned Trending topics section next week, noting it only accounted for 1.5% of clicks to news publishers in the five countries where it was displayed in the News Feed. 

You've likely noticed the Trending box in the upper right-hand corner of your News Feed page before, only to forget about it and never click on a link there again.
