A new study from Pew Research Center found that social networks like Instagram, Facebook and Twitter are all slowing down considerably when it comes to adding U.S. adult users. Pew reported the percentage of Internet-using adults for each network on Wednesday, and while Facebook, Instagram and Pinterest all increased (slightly) since 2014, the percentage of U.S. adults on Twitter didn’t change from 2014. LinkedIn’s number actually decreased, from 28 percent to 25 percent.
