Oh, awesome: the folks at Flickr have moved from a photo interface based on Flash to one based on good ol’ Ajax, and done so pretty damn quickly! I’m happiest just because the old interface didn’t always sit well with my browsing style (loading tabs in the background and then going to check them out in batches); frequently, I’d get to a Flickr page and find that I had to reload it in order to get the Flash photo-viewing box to fill in. But beyond that, the new interface seems quicker and more intuitive to me (like, for example, you can now include links in your photo notes!).
