Move over AJAX, welcome AHAH
I jest. I just think it's interesting that people have taken the time to create an acronym and development process for something that everybody has been calling AJAX anyways. AHAH is Asychronous HTML and HTTP. HTML gets pregenerated on the server and then spit into the DOM via innerHTML. This is how I've always approached it. It just seemed so much easier and faster on the client side. As the team from 37signals is famous for saying: Less is More.
