There's a benefit to many different people in posting articles, blogs, and ideas online, but not everyone is adept at the various skills that are required of a modern website; 'Cool Backgrounds' is a tool that helps anyone to create compelling images to accompany their work.
For writers, completing a blog post is only half the battle. They still need to be able to build and design a website that readers will be comfortable, and even excited, to use. Not all writers have that ability, so Cool Backgrounds helps them to do so. It provides unique, procedurally generated hero images that are free to use and simple to copy and paste as the header for one's blog.
