Today wordpress is the most popular blogging/weblog software available. It is free and licensed under the GNU General Public License, which gives your freedom to change and redistribute the code or simply just use it to create blogs. Created by Matt Mullenweg in 2003, have become the most popular publishing platform installed on more than 202 million web sites worldwide (source wikipedia: http://en.wikipedia.org/wiki/WordPress). WordPress software itself is programmed in PHP (HyperText Preprocessor – dynamic web programming language), so it requires a php hosting platform and MySQL (open-source relational database management system). WordPress have many features making not just blog platform, but a powerful content management system. Some of the features are: content management (text/media/video), RSS (Really Simple Syndication) feeds for posts and comments, static pages (e.g about page), user registration and management with permissions, post comments, blog communication tools like pingbacks and trackbacks, widgets support and others. You will particularly like the template systems which separates design from actual code. There is built-in theme editor if you want to make changes to the current theme, and theme preview/switcher where you can change the template. Widgets are little blocks that contain some information (like for example menu links or photos) and can be placed on the sidebar if the theme is widget-ready. The powerful extension system (wordpress plugins) is where developers add new functions to the core ones. For example there is the flickr plugin where you can post the latest photos from your flickr stream in your posts or as a widget block in your sidebar. Once you have installed wordpress you will fall in love with it.
