From BradA : Simone Chiaretta is doing another Ajax survey to see how things have changed since his last survey a couple of years ago. I just filled it out (you should too!). The survey can be found here . Oh, and if the suspense is killing you, I'll give you my answers: I'm using AJAX in a production application. It's part of a MonoRail application. I'm using the Prototype on the client. Technorati Tags: Ajax , Survey , MonoRail
