The OpenAjax Alliance states that it is an "organization of leading vendors, open source projects, and companies using Ajax," but I don't find any questions on stackoverflow that reference them. I am wondering if it is important to the practicing web developer. John Resig has a Thoughts on OpenAjax blog post in Feb 2007, but I can't find many other references.
I have looked at the OpenAjax Hub 1.0 as a way to do publish/subscribe messaging in the browser (similar to TIBCO PageBus, which implements the specification). Is anyone using this technology effectively in a large, public facing web application?
