I very much agree on the drop in productivity. I was just contracted to help with a Node project and just getting up to speed has been difficult. This is not all node's fault since the callbacks and such could have been handled differently.

The better examples will be in a few years when programmers have more experience with Node and the projects' code reflect that.

I won't be returning back to Node after the project though because it reminds me of earlier days writing XML with Spring.
