Picasa Facial Recognition

The facial recognition feature on Picasa (online only) is _amazing_. This was back when I had "tagged" < 1000 pics. Now I'm at ~4k and it is right about 75% of the time. This screenshot is from when I was having it search for pictures of my dad; it pulled up pictures of me and thought they could either be me, my dad, or my brother. Wow.

There is one minor issue with this one though. It was doing pretty well (except for that 4th one... don't know who that is) until the very last pic. Hm..... maybe its the shades?
