Is it always a good thing that anyone with a computer can create a website?

It is not always a good thing that anyone with a computer can design a web site. Anyone can design a website. This is true. However without being properly educated about aspects of design or having enough experience, the website might look more like a two year old just colored on the wall. Designing sites for practice/experience is one thing, but if you are designing for someone else, that person probably would prefer for you to be more professional, so that the site functions properly. On the other hand, there are some people who learn well enough as they go to be able to pick up the nuances of design quickly without encountering too many run-ins with bad design. Either way, trying to find a site designer that would fit your expectations and budget can be an arduous task.
