Here’s the story as reported by NBC. I’ll provide a brief translation below.
The company said an internal probe showed no evidence of political bias in the selection of news stories for Trending Topics, a feature that is separate from the main “news feed” where most Facebook users get their news.
But the world’s largest social network said in a blog post on Monday that it was introducing several changes, including elimination of a top-ten list of approved websites, more training and clearer guidelines to help human editors avoid ideological or political bias, and more robust review procedures.
Earlier this month, a former Facebook contractor had accused the company’s editors of deliberately suppressing conservative news. The allegations were reported by technology news website Gizmodo, which did not identify the ex-contractor.
Translation: We did nothing wrong and we’re going to do a better job of hiding it.
I hope that clears things up for you.
