The Internet is basically a limitless font of digitized information. Anything and everything can and has ended up on some sort of website at some point in the past three decades. The trick is organizing and updating that information while making it easy to access.
Web developers and programmers have the tools and skills to update websites themselves. If you aren’t planning on going back to school and need to make frequent updates to your site, you may want to consider using a content management system.
Content management systems have become increasingly user friendly and allow you to organize your website in such a way that it is accessible to everyone. The trick is finding and implementing the correct CMS for your needs and budget.
