Sites are organic—if they don't grow, they languish and die.

Sites are students—when you work on them, you embed in them all you know.

Sites are children—the offspring of your creativity, effort, and imagination.

Sites are code—they need to be maintained.

Once your site is complete, it is not complete. Update regularly. Check your links. Modify content as needed. Make sure your site is whole, and healthy, and alive.
