Did you hear about the latest Facebook study? It's left a lot of people outraged by news of an experiment conducted in 2012 that temporarily influenced what almost 700,000 readers saw on their news feeds.

For whatever reason, researchers thought it would be a good idea to mess with Facebook users’ news feeds  and then see what sorts of updates they posted. You know-positive updates after seeing positive stories and negative updates after negative updates.

Anyway, one of the study’s authors haws come forward and apologized for manipulating the feelings of people who didn’t know they were being studied.

News leaking of the experiment might have been a good thing though because it's shed a spotlight again on how Facebook deals with privacy issues.
