Wordpress is an open source blogging tool built on the PHP/MySQL pairing. While it is possible to create a blog using these technologies, Wordpress offers many integrated features and RSS capabilities.
Wordpress is easy to install on your domain and offers complete customization with a little work, which we at G&C Web Design are happy to do. It has many available plugins, widgets and themes, each of which can be edited to better suit your needs, and comes with Administrative Tools to allow you to update content easily and regularly.
The latest stable release is v3.2.1.
