“I’m changing the goal I give our product teams from focusing on helping you find relevant content to helping you have more meaningful social interactions,” he wrote.
“We started making changes in this direction last year, but it will take months for this new focus to make its way through all our products.
“The first changes you’ll see will be in News Feed, where you can expect to see more from your friends, family and groups.
“As we roll this out, you’ll see less public content like posts from businesses, brands, and media.
“And the public content you see more will be held to the same standard — it should encourage meaningful interactions between people.”
