Simblog aims to be one of the most easy-to-use and lightweight blogging platforms. It emphasizes user experience, workflow, and ease of use without neglecting usability and extensibility. It will take full advantage of what HTML5 and CSS3 have to offer without delving too deeply into experimental features. It is built on its own lightweight framework, which allows a high degree of extensibility and modularity for your blog. It uses Smarty as a templating engine (which also provides a caching mechanism), jQuery and Kendo UI for frontend design, and MySQL as a database.
