It's what you keep off. This censorship should consider quality of element and content. You build your image based upon what you show the audience.
Poor quality equals lousy perception.
Many radio web site leave me thinking a lot of stations have to improve quality before the Internet pays off. To make commercial use of the Internet you must establish a professional image. You must offer items of interest in an esthetically pleasing way. You must create an environment the User wants to return to, and you must put some thought into it. That's a receipe for disaster in any media.
