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?

From what I see, ActivityPub doesn't seem to solve the problem of sorting or prioritizing content. In fact, I believe RSS wins here, because it is easier to do this on the client side with RSS, as it is assumed the client has all the content from the RSS feed without any biased order, whereas with activity pub, it varies by provider and instance.

Sorting and filtering can be done well on the client side, and the plus side is the user can have a ton of choice here. It just so happens that our algorithms for that in the open source world are no match for the addiction-inducing ones of Twitter and others.

You raise a good point that it would be nice to have more control over which group of communities you are drawing from at a given time. (Is there a way to group subscriptions and switch between them?) It’s a bit disconcerting to see 5 tech headlines and then suddenly something about the war in Ukraine or whatever. It jars my train of thought. With an RSS client, you can group feeds however you want.

That said, my experience with RSS readers is not quite so idyllic. In the end, rather than having nicely partitioned feed groups by topic, I wind up having to separate the ones that produce content frequently but with a poor signal-to-noise from those that post once in awhile but are generally worth your time. With something like lemmy, people are helping you do the work of finding the more interesting content from that site that posts every 10 minutes.

I fully agree with you, but I think this isn't because RSS clients can't do this from a technical perspective. I suppose most RSS clients come from people with anti algorithm sentiment, but realistically, a RSS client has all what it needs to implement basic or advanced sorting and filtering.

But I agree with you that most rss readers out there have that problem.

I suppose the same could be said on the lemmy side. There's no reason someone couldn't write a lemmy app that lets you do what an RSS client does in terms of only showing content from a selected subgroup of communities.
