Introducting Javascript Object Notation (JSON)

Interesting site about the creation of a new Javascript based language for exchanging data. Quipped as the "Fat Free alternative to XML" on one of the pages. I'm still in the early stages of learning XML for myself but I'm always open to hearing the latest news about emerging technologies.

Here's the link: www.json.org

Please realize that as far as I know this technology is not widely accepted as a data-interchange format. In fact, a search on google doesn't turn up much at all, but here are some other links anyway:
