I'm working on a story map - Top 10 Reasons to Get Started with ArcGIS Online, and i"m looking for metrics on numbers of users and amount of content. One of my reasons is "Access to Existing Content".
A blog from a couple of years ago cited 1.4 million users across organizational accounts, and 17 million of web maps, apps, feature layers, etc. combined. It was already the single largest repository of geographic information, but I want my metrics to be current.
Given the pace this platform has been growing, I know these numbers have to have changed a lot, even in just a couple of years. Any a number of organizational accounts would be good to have too, if that is available.
