WordPress is a free blogging platform available to everyone. WordPress has two components, one is a free, Web-based blog-hosting service called WordPress.com. The other is WordPress.org, which provides users with software to run a more feature-rich version of the blogging tool on their own servers.
Both services offer a very easy way to blog, with administrative options to work collaboratively on one or several blogs using the same log-in. Bloggers can write their posts on a WYSIWYG editor, or switch over to a code view on the fly.
The service is best-known for its themes and plug-ins, which are created by and shared among its users. A blog owner running WordPress on his or her own server can download these themes and plug-ins, and deploy changes to the blog site instantly. WordPress.com users are limited to a smaller selection of themes, although both sets of users can customize aspects of the theme's code to tailor the look and feel of their sites.
