We're collecting lots of stats in Google Analytics (for LibX 2.0 users).
We have, unfortunately, only an unfinished prototype for how to share this information with edition maintainers. Essentially, the issue is that we must write an application that uses the Google analytics API and extract only the information pertaining to a particular edition (or editions) - Google analytics doesn't have a way to share the results of individual queries.
A student made significant progress on this, but the last mile is still to be coded - if anyone wants to devote programming resources, I'd be happy to advise.
