It's about time, Flickr
I’ve only spent a few minutes playing with it, but it’s really good so far. They did a nice job with the interface, especially “clustering” photos together as you zoom in and out.
I’m excited about this. Our customers have been enjoying geotagging support for more than a year (see Tim’s post about it), and I know Zooomr’s had good support for awhile, too. But Flickr has lot more market share, mind share, and PR leverage than the rest of us do, so hopefully this will get camera manufacturers to get on the ball and make this a standard checklist feature. Let’s hope so.
