Looks fine to me.

I'm saddened by the amount of taxpayer money that was spent searching for 5 millionaires who went missing while on a joyride in a test vehicle.

Is it though? It kind of feels like you broke up with someone but are still getting constant updates about who they're currently fucking the minute you left.

I guess that's some people's kink.

Every time it's mentioned it's only about sending e-mail to different providers, but the analogy doesn't cover for example browsing your e-mail inbox and seeing communication from multiple sources. Just covering how one individual can send messages to multiple individuals via a common protocol is only half the picture.

Honestly it's more like the old mailing lists (Majordomo days), where individuals would subscribe to a list, but that list might also subscribe to other lists themselves, and then you throw a web interface in front of it.

I know you're using the e-mail analogy to represent how SMTP and ActivtyPub are a common protocol, but I've seen the same analogy mentioned several times and I think it only serves to muddy the waters, because it's incomplete.

I'm not sure you understand how outsourcing works ...
