Today Johan van Zyl relayed a Node.js offer email in comp.lang.clarion. This is a promotional offer which is designed to get you signed up on a $29/month plan at Learnable.com. The first month is just $9 and you get the Node.js course and ebook. I haven't had any experience with Learnable yet, and it's probably well worth the $$$, but do note that you can cancel any time if you just want to drop the $9.
