resources to get started with node.js

There are quite some blogs and websites about "getting started with node.js". Here are some resources that I found most useful:

• How To Node: maybe the best blog covering latest development in node.js with many core node.js developers and users.
• Up and Running with Node.js: OReilly's new book, freely available online as of now
• Mastering Node: another great online book
• Node by Example: a series of examples to get you started with node.js
• The Node Beginner Book (WIP new)
