I've been developing a node.js + express.js web app, but the problem I keep running into is project or blog abandonment. I realize node is still relatively new and going through some growing pains perhaps.
What are some node resources that are still active for learning how to build web apps with it?

These are my book marks for learning node. They have been helpful. But ofcourse, node changes alot, and by the time you probably read or watch some of these, there has been a new version of node. Be sure to watch the git page node, and pay close attention the the changes.
