Face recognition is a very handy feature to have for photo management. Between that and Geotagging, my organization of photos has changed quite a bit. Definitely glad iPhoto added it in the 09 release, and other apps are also adding it.

Face movie in Picassa 3.8 interests me enough to play around with it. Time to see how long it takes to go through my iPhoto library to be able to make one of these for my sisters kids.
