Well, here is another case about user retention (I don't know how representative it is): some gaming communities use a FANDOM wiki as their main documentation and reference. When players have a question, they might google to find the relevant wiki page, go directly to it, and not come back for several days or weeks. (For example, the Rec Room wiki has almost a thousand daily page views but there is only a handful of active editing users.)

Thus, a gaming community as a whole might create quite some traffic without showing a high Day 7 retention rate. I would assume that Day 30 retention rate makes much more sense in those cases. However, I understand that FANDOM would be more interested in daily visitors. But the audience that would come back daily for anything that FANDOM has to offer might be very different from the audience that would come back every once in a while to the wikis, which is the audience that many power users are targeting. I think that chasing these potential daily visitors at the cost of fewer customization features for the desktop experience might alienate more and more power users.
