flickr uses ajax?

while adding descriptions and titles on my photos on flickr, it occured to me: is flickr using ajax? when i click on titles of two or three photos at once, modify only one of them, and click save, the edit section of other photos don't disappear. if it's a traditional form based application, the whole page should've been refreshed.

neat!

it's like newton's apple and columbus' discovery of america.

it's been there all along, I just didn't realize it.
now, i see! i'm no longer a blind.

ajax isn't future, it's present.
more reason for me to learn CSS and javascripts back from my old '97/'98 UI skills.
