I'm a co-creator of the NASA Wikis and I wrote that 5 Year Wikiversary page. Early on we thought creating one wiki for every group was the way. We were wrong. It's better to have as few wikis as possible. We now structure our wikis based on the level of data protection. I think the intelligence agencies do this too. See https://mediawiki.org/wiki/EMWCon_Spring_2019/Creating_the_International_Space_Station_Wiki_by_Merging_Topic_Wikis https://mediawiki.org/wiki/EMWCon_Spring_2019/Creating_the_I... for a talk about why and how we merged wikis after learning the hard way. I link to other videos and info about our work on my user page: https://mediawiki.org/wiki/User:Darenwelsh https://mediawiki.org/wiki/User:Darenwelsh I need to start exploring the stats again as we're celebrating 10 years this coming November.
