@akkartik right. that’s kind of the sense i’m getting.
it’s a pretty trivial thing, notice when RSS items or collections of items “finalize” in feeds (whatever that means, i have a meaning) then notify subscribers. initially that was e-mail, but i’m like, well activitypub bridges would be cool too, what if i just let finalization be an “event” and hang off kafka different kinds of responders to those? nice it’d break things into simple pieces, but kafka’s kafkaesqueness might overwhelm that.
