Using NodeJS to publish rich front-side web pages into cloud

With the help of PAAS, such as Node.js clouds: http://www.nodejitsu.com/, it is a very good idea to publish some static articles by using NodeJS + free cloud services.
Somethings like this:

http://docs.jit.su/articles/getting-started/how-to-use-util-inspect

developing everything on your Unbuntu, and using jitsu deploy to publish in the cloud for free.
The benefits of this over worldpress.com is that you have total front-side controls without limitation. For example, wordpress doesn’t support front-side javascript, AJAX, and server-side scripts; and web hosting server is not free of charge.
Only cloud-based NodeJS support such rich and powerful front-side webpages, and back-end scripts without charge.
I will publish my samples by using this way.
