@ceejbot @ummjackson I think speed vs perceived speed is the Crux. Super latent is fine if we don't know it's happening.
@reconbot @ummjackson @ceejbot I think I ran into a case where speed vs. perceived speed becomes apparent. When I reply to a toot on another instance, an optimization makes my reply show up immediately; but if I reload, it's not there, and doesn't show up again until it comes back via federation. Which seems to take quite a few minutes.
@jef @ceejbot @reconbot @ummjackson Boosting can have a similar type of situation - I've seen a couple instances where I've retooted summat but it shows as a 500 status; doing it again has it complain that 'reblog already exists'

@ceejbot @reconbot @ummjackson @jef In this case, reloading did show that the status was appropriately applied.

Kinda fascinating.
