Hey all!
We've released a highly-aggregated dataset of readership data - specifically, data about where, geographically, traffic to each of our projects (and all of our projects) comes from. The data can be found at http://dx.doi.org/10.6084/m9.figshare.1317408 - additionally, I've put together an exploration tool for it at https://ironholds.shinyapps.io/WhereInTheWorldIsWikipedia/
Hope it's useful to people!
