Anyone well known who wants to speak out about what’s been happening on reddit? Louis Rossmann? Apollo dev? John Oliver (one can dream)… or maybe former Reddit mods who were kicked out?
Anyone who has a story and who understands they’d have a massive impact by giving an exclusive AMA on a Lemmy or Kbin instance.
This could be announced a few days in advance to make sure all remote instances follow the AMA community.
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 https://join-lemmy.org/news/2023-06-17_-_Update_from_Lemmy_after_the_Reddit_blackout 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.
