Federated social media from before it was cool
(lemmy.world)
It's funny when armchair experts insist that the fediverse won't catch on because "federation is too hard to understand" when arguably the most widespread communication system on the internet follows the same model
You forgot both 'Don't send too much email' and 'Fail to send enough email' as qualifiers, as well.
Which I think is the big thing that hits more people than anything else, since 'too much traffic' and 'not enough traffic' are not defined and so you can easily be caught by one, then the other, then end up in purgatory.
(This is mostly a Microsoft problem rather than a Google problem, but still.)
