YouTube has added blur. What that means is that you can blur out faces of people in protest to protect them or in the case of the hack group Anonymous, you can stay well… Anonymous. This is still an emerging technology so be warned that the feature may miss out on faces.
You’ll be able to preview what people’s faces look like before you post the video for the world to see. The video I saved twice, a new copy with blur and the unedited original. The feature is rolling out to the site last week. Go give it a try.
