> Facebook’s algorithm isn’t surfacing one-third of Chicago Tribune’s posts Of course. That's the whole premise of the FB Newsfeed. It started in late 2011 - up to that point the news stream was in chronological order and you saw all posts (depending on your geographic the feature was enabled maybe on a different date). Then the newsfeed showed what FB algorithms provided you depending on your click-, browsing-, friend- and like-history. It's called a filter-bubble, you suddenly see just mote of the same, no variation. It marked the tipping point of FB as social network tool (at least for me).
