Maybe you want to deploy a code blog quickly. Maybe you want an excuse to play with NodeJS. I don't know what it is you are up to but here's a quick guide to building your own wtfjs. This requires a Heroku NodeJS access, of course.
$ git clone git@github.com:brianleroux/wtfjs.git
$ cd wtfjs/
$ heroku create --stack beech
$ git push heroku master
You're done!
