Stop the Visual scourage!
There is a flood of designers and computer artists, becuase there is a flood technology. Unfortunately, they are not all good and in several cases they are just plain bad. That's where BadDesignKills.com comes in, it's propaganda by professional designers who want to make the world a better (designed) place. Not to mention, it is an opportunity to "fight" back and have a little creative fun at the same time.
There is a lot that can be said for the quality that businesses should be expected to have and deliver, advertising, marketing, and design should not be an exception. I can go on and on about how some owners of businesses want what they like, but forget what their customer wants (it's not always the same thing) or the business owner has a young releative who owns a computer. Unfortunately, just becuase you have a computer doesn't mean you can create a high quality design.
In the end, the best thing is to ask a lot of questions. Think about what you want to accomplish in your website, brouchure, or flyer. And don't forget if it is hard to read, too much small type, or corny artwork, chances are the average person looking at it will not look at it for very long and forget what you were trying to accomplish. In the end, find a designer that you like the their previous work and work with the designer don't fight with him or her.
