Both from a design point of view and from a web development point of view, icons are seriously an invaluable resource and a powerful tool. They work on everything from navigation to section headers, and can take your content scan-ability to a whole new level for your users.
However, their inherent simplicity deceptively masks the amount of time and love required to create quickly recognizable icons that really work for your users. It takes time, iterations, discussions, and even a healthy discourse or two to ensure that a set of icons compliments the brand and the experience you provide to your site's visitors.
Iconography, good iconography, strives to convey invisible reality in a visible form.
