Last week, Facebook made a small but very important change to Instagram. When I like a photo in the updated Instagram app, “Ellis liked a photo on Instagram” will no longer be automatically shared back to Facebook. The same goes for photos posted to Instagram, which won’t be automatically shared on Facebook unless you deliberately tap the Facebook button in the app’s sharing screen. The update effectively removes Instagram’s ability to automatically share anything back to Facebook, and on Tuesday, Facebook is announcing its plans to take the idea much further. Automatically posted stories from apps like Pinterest, Farmville, Spotify, and RunKeeper are going to show up less and less in the News Feed, and Facebook will discourage developers from adding auto-posting to their apps at all.
