I read this post on Natalie's blog about the new features on Picasa. Jed and I are obsessed. We've spent all of our recent free time (and time that shouldn't be free) tagging people in the thousands of photos we have on our computer. Check it out. Right now, I still have almost 3,000 unnamed people to tag. But it's pretty cool how it automatically figures out groups of people that it thinks are the same person. I'm finding it especially difficult to tell apart baby Buddy and Baby X, but the computer has been doing a pretty good job of it. Very fun. But don't get started if you don't want to become obsessed.
Plus, it's a great way for your kids to really measure fairness when they see that you have over 2,000 pictures of their sibling, and only 1,500 of them.
