Content Management and CMS
A web site is like a garden. You plant a seed, you water it and care for it, and it grows. A web site is much the same, you start out with just a few pages, then you add a few more, then you add a new feature here and there and before you know it, it starts to grow.
With your garden, you must tend to it. You must clear the weeds, and prune your plants to keep them healthy and strong. Your site is just the same, you must tend to it or it will grow wildly, it becomes unmanageable, and eventually becomes obsolete.
