A traditional webpage with a few images and text, and maybe a few pull quotes is compact and familiar way to communicate.
Those wanting something a little more visually engaging have often used ESRI’s StoryMaps, which offer a richer viewing experience through the way diffrent elements interact with each other as you scroll through the story.
One limitation of StoryMaps is its opaquenss. Your story, your data, and design choice go into a database that you might eventually lost access to. It’s hard to preserve your story in native form when entirely dependent on another platform.
