I've started to play with the beta version of the new Story Maps. I like its simplicity and how effortlessly it moves me, as the reader, down thru the story. It also implements improvements that some of us have been asking for, like larger popup windows.
Short sighted ingrate that I am, I started looking for elements of my current story maps and worrying about the ones I couldn't find. The big one, for me, that I haven't yet noticed, is the ability to jump from one part of the story to another. My Map Stories work more like little atlases than stories. My readers aren't going to be interested in reading thru them sequentially as someone reading an interesting magazine article might. They will want to the map on the tab that they need, and not to have to scroll thru a bunch of other stuff.
