@wikipedia really needs to do some user/editor #ethnography
https://en.m.wikipedia.org/wiki/Academic_studies_about_Wikipedia contains lots of info on studies, but I can't see anything about how editors interact with the site. It would be be particularly useful to interview people who have been editors in the past and have stopped. And ideally block that across demographics
I used to edit a lot, but I lost interest after an mildly obnoxious edit war over the interpretation of a low-n metaanalysis (also lack of time)
