There are quite a few reasons to choose a CMS (or, content management system) as your website solution. The key advantage is simply flexibility. With a CMS, you can:
1) edit content without the hassle of going through pages and pages of code, in a fully scalable environment.
2) Make updates as they come to you, instead of waiting for a designer to make the change for you.
3) leverage the flexibility of an open-source content management system for a wide range of purposes. Create a small business site and stake your claim on the web, or set up a network of sites on the same domain. All this flexibility stems from the “framework” approach used by content management systems, where a user can expand the features used on the website with as few as 2-3 clicks.
4)Add a contact form, galleries, a product page, virtually anything you can think of – developers have added it.
The variety of features depends on your choice of CMS. The most popular Open-source Content Management Systems are WordPress, Joomla (formerly mambo), DotNetNuke, Drupal, PHP-nuke, MODx . I currently specialize in WordPress, Joomla, and DotNetNuke.
Each CMS generally has it’s pros and cons, and some may be better for business/enterprise needs, and some may be more suitable for personal and social networking sites. I can offer guidance and consulting based on your particular site’s needs.
