Last night I tried the new "name tags" functionality in Google's free photo management software (Picasa).  Here is a link to a description: link.  It goes through your photo collection and finds all the faces.  It groups the faces it thinks belong to the same person and and allows you to relatively easily assign a name to each face.  In the past I manually tagged photos in Picasa but gave up because it was so time consuming.  This is a nice way to do it quickly and semi-automatically.  It only works on photos you've uploaded to your web album, not the photos that are just on your local computer.  It's cool regardless.

For the benefit of all of the ladies, here is a link to a slideshow featuring photos of yours truly: link
