Facebook Photos continues to roll out new functionality. When uploading pictures yesterday, I noticed a new post-upload flow: "Who's in these photos?" It is important for a few reasons. First, it shows that Facebook is focused on driving user tags. You can also tell through other features / tests like this...
Second, it seems to be pretty good at facial recognition (or at least similarities). Notice here that I uploaded five pictures - all of our son Dillon. It clustered three photos and two individual photos. Not bad - and as users tag more and more photos, the recognition will get better.
Third, the speed at which Facebook is rolling new Photos features is impressive: higher resolutions, new layout, better tagging, etc.
