Well, if you're one of the millions of people who have a website or want to have a website, using a tool like Joomla could be a great facilitator for getting your website built in such a way that you can update it anytime you like. One of the drawbacks to having a website built for you the old "static" way was that if you wanted to make changes to the site typically you had to have your designer make them for you, as most people did not have the capabilities to make their own changes. Joomla changes that. You probably still don't have the capabilities of making the site, but if you have a dynamic, CMS site built for you using Joomla, you will be able to make changes, add photos, even add new pages and so on. The learning curve is pretty small.
Joomla is what is called Open Source software, which means that it's not owned by anyone who will charge you to use it. There is a Joomla organization that oversees the development of Joomla, including managing security issues and new releases. There are thousands of people, developers, involved in improving it and creating thousands of extensions that add functionality to the core software. This large community of developers, not to mention users, makes Joomla a very popular tool for website development and design.
So this free, Open Source, website development tool, that is easy to use, therefore empowering its users, and that is so widely supported by an organization and large community of developers and users makes a pretty compelling argument for why you should care.
