Until natural language processing improves, only humans can tell what’s important. So Facebook has started rolling out the option to pay to promote a friend’s posts and get them seen by more people. This will help critical posts bubble to the top of the feed, and let Facebook earn some money, too. The feature respects privacy controls, but could still make you look like a self-important prick. Facebook began testing the ability to promote your own posts in May 2012 and rolled the feature out to the U.S. in October. See, your average Facebook post only gets seen by about 16 percent of your friends because they aren’t online soon after you post, or you never interact with them on Facebook. Promoted Posts artificially boost your posts so they appear in the news feed to people Facebook wouldn’t have shown them to. The option has enraged some people, making them feel like they’re being extorted to communicate with their friends.
