Ruud would likely bring in some Masto + other fediverse users who haven’t tried Lemmy yet.
Allowing the core devs to let us know more about them outside of their coding + assumed politics (we really should have a link to their recent post join-lemmy.org/…/2023-06-17_-_Update_from_Lemmy_a… and make it a rule in the AMA to not beat that dead horse) would likely make lemmy more approachable to those on the borderline. Any way it would go would still be better than u/spez’s.
I think any of the three would be large enough that we can stress test community interest/behavior, mod abilities, and instance/community load.
