This article is definitely a advertisement :p
Last year, I made two Jekyll themes, one is Freshman, the other is Freshman21. Freshman is a simple html/css theme that I made to learn Jekyll and css. Freshman21 looks like WordPress theme. A tribute to Twenty Twelve and Twenty eleven. I send a pull request to jekyllthemes.org, thanks to Matt Harzewski, my theme is already updated to the website in January.
If you are a fan of WordPress theme and try using Jekyll to build your own blog, may the Freshman21 be with you.
Freshman21 has two version: one-colunm and two-columns.
Welcome to submit new request to the theme at github.
