http://www.open-blog.info/ Open blog is a free and open source blogging platform built using the CodeIgniter PHP framework and released under the GPL v3 license. It provides users with a very powerful yet easy to use interface which makes blogging simple and enjoyable. We keep our source base well factored so the developers can easier continue refining the development version, add their own modules and features, fix possible bugs, and most importantly, do their job. You can read more about the features itself on the Features page, or if you would like to get started, go to the Getting started page and follow the step-by-step instructions. 基于框架开发的blog，代码自不必说，非常漂亮， 就是中文支持不太好，也只能说CI对中文不友好。。做英文站朋友可以试试。。
