I have a blog built by powerful Wordpress and quite like it. There are plenty of great plugins and themes to help you customize blog.
Octopress is definately built for hackers. Pure words and command lines. So I think building a Octopress blog would be a good way to learn and share.
The advantages of Octopress:
- static page
- hosting on github pages
Setup Octopress is easy if you are familar with ruby and git.
Then install dependencies and default theme.
Using third-party theme
