Kurt Gessler, deputy editor for digital news at the Chicago Tribune, posted that since January, the Tribune has seen a significant drop in the reach of its posts on Facebook, despite having grown its fan base.

The post sparked a sigh of validation across publishers as others chimed in on social media that they're seeing similar declines.

Facebook's news feed algorithm changes have been part of publishing reality for many years. But to Matt Karolian, director of audience engagement at The Boston Globe, "last month was probably the worst we've had in reach in about a year. The fact everyone else is seeing it is a little bit troubling."
