Over at GigaOm, Mathew Ingram examines the political implications of algorithmic filtering on the use of social media as a news source, specifically comparing the differences between Facebook and Twitter in the coverage of #Ferguson.

In a nutshell: over on Twitter, which is largely “unfiltered” but for the people you choose to follow, #Ferguson exploded very, very quickly. Meanwhile, on Facebook, where content is filtered through a bunch of esoteric algorithms based on your past behaviour, it took quite a while for any information about the incident to start trickling through… assuming it did at all.
