I know they’re quite different technically. But practically, what does ActivityPub unlock that was not previously possible with RSS and basic web tech stack?
I think I have an idea of the answer. RSS may provide a way for users to “subscribe” to content from a feed, equivalent of following and putting it in a unified feed.
But it does not have a way for users to interact with the poster, like comments or likes. This may be possible with a basic web stack though, but either users will have to make accounts on every person’s site, or the site has to accept no user auth. (but this could be resolved with a identity provider standard, like disqus does)
I suppose another thing activityPub does is distribute content to multiple servers. Not sure if this is really desirable though?
Anyways, did I miss anything?
I am responding to your point about RSS not having ability to discover new content whereas activityPub can. I summarized my point in the last paragraph. To reiterate, I agree that RSS doesn’t have built in discoverability, but whatever ActivityPub has is not solving the discoverability problem. Let me know which part you don’t understand please and I’d be glad to clarify.
