This is where you have a picture under which exists a whole pile of other pictures.

On Flickr you see these all the time. Click on a picture at the top, like this one shot by Steve Keys:

What do you get? More photos, right?

But skimming lets you see the photos below just by running your mouse pointer across the photo without visiting the page below it. The picture just changes as you drag to show other pictures. It’s one of those things you need to see demonstrated. I’m sure over at Apple.com you’ll see lots of video of this. The new iMovie makes a lot of use of skimming. So does iPhoto and .MAC’s new Web Gallery.

It’s one thing I saw and instantly asked “why doesn’t Flickr have this?”

More analysis to come. In the meantime every blogger who was there is going nuts over on TechMeme. Apple sure does know how to get the world’s attention.
