Checked it out - left after a click and a few scrolls because I could find no actual examples of what I would get if I signed up. I spent probably 10-15 seconds on the page which is probably what most folks would do. If I can't find where you show me actual examples of the product that I would use, I will close the tab.
Really like this. There's a bug in the Map element where annotations don't work properly at the world scale. Otherwise awesome. Looking forward to seeing where this goes. One great addition would be a JSON builder or the like that would allow callouts to trusted datasets for dynamic infographics.
