Trusted means has non zero trust rank. Without this filter anyone could drive raw retention number to whatever they like it to be by generating lots of fake accounts.

Also, I would say that absolute retention of 'trusted' users isn't that indicative, but the month-over-month changes to it would be useful, no matter how 'trusted' is defined. Unfortunately, retention hasn't been growing, which to me is puzzling, as if we had no progress whatsoever on UX. Would be great if someone experienced set up a nostr-retention-task-force and dug into this. 

 I think that’s because there hasn’t been any onboarding improvement in terms of content surfacing. Global is still global and looks like a mess last I looked. For the longest time we were just recommending bitcoiners as people to follow. Casual glancer propbably can’t relate .
