Most of the discussion concerning the Macromedia.com website beta has focused around its use of Flash. However, I think that one of the most important / coolest things about the website is the fact that it has been completely re-written using ColdFusion MX.
Christian Cantrell notes this, and I have to agree with him when he says:
If there was any question whether CFMX was ready for the enterprise market, I think we now have an answer.
Btw, there are still a few pages which have not been transitioned over to ColdFusion MX yet, including the feedback form.
