Move to Hexo

Today, I moved my blog from Wordpress to Hexo. I use github.io to host the blog.

The reason I choose Hexo not Jekyll mainly is I am more familiar with Node.js than Ruby so I can write plugins easily.

Hexo is a very powerful static content generator which converts MarkDown posts to Html.
