Inside Facebook’s (Totally Insane, Unintentionally Gigantic, Hyperpartisan) Political-Media Machine

a lot of media sources you don’t recognize ... a new and distinctive sort of operation ... political news and advocacy pages made specifically for Facebook... engineered to reach audiences exclusively in the news feed... Occupy Democrats; The Angry Patriot; US Chronicle... together make up 2016’s most disruptive, and least understood, force in media.
perhaps the purest expression of Facebook’s design and of the incentives coded into its algorithm... truly Facebook-native political pages ... cherry-picking and reconstituting the most effective tactics and tropes... to get them to share ...
From a user’s point of view, every share, like or comment is both an act of speech and an accretive piece of a public identity... A newspaper-style story or a dry, matter-of-fact headline is adequate... even better is a headline, or meme, that skips straight to an ideological conclusion ...
Terry Littlepage, an internet marketer ... runs a collection of about 50 politically themed Facebook pages ...push visitors to a half-dozen external websites, stocked with content aggregated by a team of freelancers.... In a good month, Littlepage’s properties bring in $60,000.
such news exists primarily within the feeds of the already converted... In front of largely hidden and utterly sympathetic audiences, incredible narratives can take shape, before emerging, mostly formed, into the national discourse.
