Facebook is tracking ‘trends,’ and The Washington Post is tracking Facebook (and Google and Twitter)

“Before Gizmodo published allegations that Facebook’s editors were biased, no one thought much about the “Trending” stories the site promotes in the top-right corner of its home screen,” Caitlin Dewey writes, but the section’s mishaps shows the fallibility of algorithms. To better understand what kinds of news stories and topics the trending news section tends to feature, The Washington Post is logging the stories that are trending each hour on Facebook, Google and Twitter. Those topics are then being compiled into a daily news digest, and the Post says it will be tracking “the priorities and timing of trends on each site.”
