You're right that people should try out stuff before criticising, and in general I support the notion; yet I fully understand people who don't want to jump ship onto very new things because leaving a well-established environment for an immature/unstable one can (but doesn't have to) be a risk. At least Coffee is relatively easy to leave - just take your compiled code and get rid of the source.
I'd also like to add for the rest: what convinced me to try Coffee was @jsjabber podcast with the author http://javascriptjabber.com/017-jsj-coffeescript-with-jeremy... - I think it explains the concepts pretty well (I recommend the whole podcast btw, it's great) and I encourage to listen to it if somebody is curious and wants to try out.
