For many years in online
advertising circles, it was accepted as a truism that Facebook is “just a
platform.” Unlike a publisher, a platform has no say in what content flows
through its pipes.
That idea was always flawed
as it overlooked Facebook’s Edgerank algorithm which displays the content it deems
interesting for its users, while burying that which it deems less so. As Josh
Constine from TechCrunch put it at the time: Facebook controls the news feed
like an editor-in-chief controls a newspaper’s front page. Facebook did have
one key constraint: it would only display content that was published (or
engaged with) by someone in a user’s network. The algorithm decided which piece
of content to display, but it could only choose from a user’s self-selected
network.*
Despite the existence of an
algorithm designed to curate content, the idea that Facebook was a neutral
platform persisted in ad land. Algorithms enjoy a certain inscrutable air on
Madison Avenue. They are magical black boxes out of which billion-dollar businesses
bloom. Years earlier, Google’s algorithm accomplished the God-like task of
“organizing the world’s information”, if Facebook’s algorithm could do
something equally impressive in “social”, it was hardly Madison Avenue’s place
to question it.
Then of course, the "Reach-gate" scandal happened and the myth that Facebook was a neutral platform vanished along with organic reach.
Facebook insists the change to the algorithm addressed user experience, and not
revenue goals, but nevertheless, Madison Avenue learned a hard lesson: Facebook
and its algorithm should be viewed with a healthy skepticism. (Overheard
predicted the tweak to organic reach 2 years before.)
Now, it may be time for the
general public to learn the same lesson.
The Boston Globe is reporting
that Facebook is testing a “related articles” feature that promotes content
that it deems relevant for its users. Sound familiar? Except this time,
Facebook seems willing to introduce what I’ll call “foreign content”, in other
words, content that was never published or engaged with by anyone in your
network. While this could certainly be
testing ground for an Outbrain-like ad product, this feature has broader
implications.

At last count, Pew reported that 30% of Americans
get their news from Facebook. Now, it
seems that “getting your news from Facebook” has a literal interpretation that
Pew never intended.
*There is a notable exception to this rule: beginning in 2012, advertisers could pay to insert their own content into a user’s newsfeed without being part of the user’s network.
