https://bespin.mozilla.com/ Would you guys do me a favor and do the one-step registration for BeSpin and tell me what you think? If there were a great IDE for a new language, and it was based on BeSpin, would you consider using it? What do you think of BeSpin? Nice? Performance is ok? Usable? Shite? Note: IE does not support Canvas, but the link will work in all other modern browsers.
