Facebook are changing their News Feed algorithm again, surveying users to rate posts they may not want to see. The company revealed in a blog post that they have started streamlining News Feeds based on the results of the survey. According to Mashable, the new algorithm will favour ‘relevant’ and informative stories and place them at the top of your scroll. The company has reportedly been reviewing ‘tens of thousands’ of responses, using "qualitative feedback to show relevant stories.” Facebook now plan to only show you posts based on the likelihood of you having an interest in seeing a particular update, as well as how likely you are to engage with a post by ‘liking’, commenting or sharing the news update. Explaining the move in a blog post, Facebook wrote: 'News Feed will begin to look at both the probability that you would want to see the story at the top of your feed and the probability that you will like, comment on, click or share a story. We will rank stories higher in feed which we think people might take action on, and which people might want to see near the top of their News Feed.' You can still opt to manually choose friends to ‘Follow’ – whose updates will always appear at the top of your page. Just be aware before you add your ex's new squeeze from afar, that you can check to see who chooses to 'Follow' you on the social network. You have been warned.
