So as if Google didn't know enough about you, it now has the capability of recognizing faces in your Picasa albums. (For those of you who don't know what Picasa is, it's Google's version of Flickr, which is a popular online photo storage and sharing service.)
Draw a little box around a face and Google will analyze all your photos and find the ones that person is also in. You can then label all those pictures for easy reference later. So, for example, I'd highlight my mom's face in one image and Google finds the rest of the pictures I've taken of my mom. I label them all "Mom" and even link the picture to my contacts in Gmail.
So, yeah. Google now has pictures and contact information for everyone in your photo albums.
