Overall their display is nice, but takes awhile to load.
And they do NOT, as of yet, have on the current Story you are viewing, a dropdown list to choose where you want to go next. Therefor you have to, no choice, go back to the first page (mouse click) let the page load, then scroll way down (those little thumbnails take up room) and choose the next site (mouse click) you want to go to.
They had a good thing, but screwed it up somewhat by leaving that feature off. And don't try doing it on your smartphone.
I like the map option that he's designed, now just have to get NWS to stabilize all the URLs.
