this post was written a few mouth ago. And for some reason, my idea had changed.
if you are a geeker, and you use github, you must have know github pages, and something like Jekyll or Octopress.
I tried Octopress last year, and find it quite complex to use. As someone in V2EX said, Octopress is for someone called "SBC", i do think so (but Octopress’s default theme is more beautiful).
then i tried several other static website generator, like nico, hexo etc. i found that hexo quite easy to use, the properity of written in nodejs is friendly to frontend developers.
