Meh, it's just standard JavaScript (not even CoffeeScript!) to build Yet Another Blogging Platform. A well-loved (467 watches, 49 forks) node.js blogging platform already exists, authored by @creationix who is actually _employed_ to build nodey things for WebOS: https://github.com/creationix/wheat So I would recommend reading the code of that project first, rather than me-too code from someone who thinks that deploying via DropBox is cool.
Wow, patronise much?
