Facebook was embarrassed over the weekend after it replaced its human editors with an algorithm, which then allowed a fake news story to appear on the site’s “trending” sidebar. It gets worse. Trending on Facebook yesterday was an x-rated video of a man performing a sex act on a McDonald’s McChicken sandwich – choking the McChicken, if you will. Previously Facebook’s trending stories were monitored by a team of real people, who could filter out fowl content like this. This weekend the algorithm was set loose to decide what should trend. With predictable results. I’m not loving it.
