Facebook made tagging and sharing photos easier with its new face detection algorithm, a nifty little feature Facebook acquired when it purchased Divvyshot back in April. No more clicking on photos to select the faces of your friends as the new face detection feature will scan your uploaded photos and automatically select the faces in the photo. Once selected, Facebook will prompt you to tag the photo with the names of your friends.  Though it is somewhat rudimentary in its current form, Facebook promises that improvements are coming down the pipeline. Any Facebookers out there excited by the prospect of click-free photo tagging?
