Octopress is Jekyll blogging at its finest.

• Octopress sports a clean responsive theme written in semantic HTML5, focused on readability and friendliness toward mobile devices.
• Code blogging is easy and beautiful. Embed code (with Solarized styling) in your posts from gists, jsFiddle or from your filesystem.
• Third party integration is simple with built-in support for Pinboard, Delicious, GitHub Repositories, Disqus Comments and Google Analytics.
• It's easy to use. A collection of rake tasks simplifies development and makes deploying a cinch.
• Ships with great plug-ins some original and others from the Jekyll community — tested and improved.
