Boys with toys...

I'm always surprised at what horrible things web developers can actually do in their work just to use AJAX stuff. I won't hurt anyone because there would be many useless deaths, but guys... use your head! A user wants interfaces to look nice, but not to hide the whole screen while reloading a single block (where's the point of using AJAX?), and they don't want to have to click on every single element to extend it just to be able to see data, either.
