Ajax is an open source territory

A poll on Ajaxian.com had response showing that the overwelming majority of respondents were using Open Source ajax libraries. The most popular libraties are Prototype,JQuery and Extjs. The only proprietary solution with significant response was Backbase.

Extjs' rise in popularity is impressive, as is Jquery's. Also of note is the quasi-disappearance from the responses of popular early players as xajax and Rico.

Though this poll is no scientific truth or statistically representative (open source enthousiats are more likely to visit Ajaxian than some corporate developer coding only for the money), with more than 2000 respondents it still give an idea of some trends.
