In light of recent concerns about information filtering on social media, Facebook acknowledged the presence of filter bubbles and has taken strides toward removing them.  In January 2017, Facebook removed personalization from its Trending Topics list in response to problems with some users not seeing highly talked-about events there.  Facebook’s strategy is to reverse the Related Articles feature that it had implemented in 2013, which would post related news stories after the user read a shared article. Now, the revamped strategy would flip this process and post articles from different perspectives on the same topic. Facebook is also attempting to go through a vetting process whereby only articles from reputable sources will be shown. Along with the founder of Craigslist and a few others, Facebook has invested $14 million into efforts "to increase trust in journalism around the world, and to better inform the public conversation”.  The idea is that even if people are only reading posts shared from their friends, at least these posts will be credible.
