What is up with templates?

I was cruising through craigslist and found a listing in computer jobs from a person who started to make a website on trendy sites.  This person did not know what they were doing and needed someone to help put the site together.  This article that I am linking has useful information about templates.  The bottom line, in my opinion, is that the design could be the easiest part of making a website, the part that takes time and attention is adding your content, and placing the content where it should be, and making sure the website is programmed to function in a way that is helpful to your business.  This article makes a few good points both in favor and not of using templates.  One thing that I saw in the downsides is that a template is set for specific sizing, and if you have more content for one area than the template allows, it could misplace everything on the page.  For instance, if a template has a space for an image that is 72px by 72px, and you try to put an image that is 225px by 225px in that spot, your image will take up a lot more room on the page than the way the template shows.  If you find a template style that you like, you can always show that to a designer and developer, and they can make a site for you that looks just about the same.
