There is a difference between sales marketing and marketing a product because it’s based on a content management system. WordPress Theme Demonstrations are a primary example of what I’m talking about here.
My first WordPress theme problem comes from the demonstration itself. Sure it looks pretty, but how is it built. Am I going to install 400 plugins to make the homepage work? Do I have to buy a plugin, that the developer built, in order to use the WordPress theme in the first place? Am I required to switch religions and claim a new faith in order to change church themes? These are real problems new WordPress users have.
