The world's largest social media network, is also one of the biggest news platforms - so allegations of Facebook's bias towards liberal news issues have triggered a lot of scrutiny, both from outside and from within.
Earlier this month, New York tech site Gizmodo reported that Facebook has been routinely manipulating the platform's 'trending' topics in order to suppress conservative agendas.
Facebook essentially controls the marketplace of ideas, and that's a very powerful thing to control when you're living in a democracy.
Facebook calls itself a 'content neutral technology platform', where users are able to connect with friends and family, read news and consume content from around the world, and then share what is meaningful to them.
But as the site continues to steadily grow and evolve into the world's most powerful media site - with over 40 percent of all US-based news traffic coming from Facebook - reactions to the report have culminated in a call for a congressional inquiry into the allegations.
Many journalists and writers have been tracking the Facebook story and its implications. These extend beyond the issue of the 'trending' topics story - which Facebook founder Mark Zuckerberg has announced will change after meetings with notable conservative leaders around the country.
So what does this 'abuse of trust' mean for Facebook as an information gatekeeper and, more importantly, how does this affect the end user?
