There are so many different aspects to designing and maintaining a website, that it’s difficult to have all the talents in just one person.
Here is a nice description of the differences: http://www.toondoo.com/toondoo/View.toon?param=32108
Do you want the site to work? Or just look pretty? Balance for affordability, Or get out the checkbook for a truly customized masterpiece.
Brian at Seven Sages is more technical and focuses on the functions of the website. So, he works with the artistic/graphic designers to make sure the website has the right look. Sometimes it’s frustrating for the Graphic Designer since their vision may look fantastic but may not work on the web. Sure, a programmer can make the artistic site work, but at what cost? Hours, even weeks of coding to bring a ‘vision’ to the web. Thousands of dollars?
